[Mining traction **](https://vonsch.sk/solutions/traction/en) ## High-speed drives Based on the market requirements for frequency converters for high-speed motor drives of cutters, grinders, spindles, we have developed high-frequency converters **UNIFREM VF**. This is a special hardware and software modification of **UNIFREM** frequency converters, enabling the output frequency up to 3000 Hz, with the PWM switching frequency to 20 kHz. If you have any comments, questions or requirements, [request a solution proposal](https://vonsch.sk/request/en) - an engineer will respond with a relevant answer. ## Servo drives There are a number of servo drives used in industry with various functions made by different manufacturers. It is quite common that our customers are asking us about a possibility of replacing the existing servo system with induction or synchronous motor. And thanks to the rich list of features of new software UNIFREM drives and its peripherals, it is often possible. If you need to design and implement a servo system with our converter for your machine, We are able to help you with this task, from the beginning of the development to the successful completion of functional tests of the machine.

VONSCH manufactures frequency converters in the range from 0.37 kW to 1400 kW. In the case of requirement of higher power frequency converter, [request a solution proposal](https://vonsch.sk/request/en). Standard range frequency converters: - **[UNIFREM](https://vonsch.sk/products/unifrem-400/en)** - the flagship of VONSCH, versatile, modern converters built with the best elements, having rich software features. They are available in the following options: **[UNIFREM 400 ...

Despite the regular frequency converters, recuperative converters are equipped with controlled rectifier allowing bidirectional power flow. Benefits of Active Front End: - The possibility of supplying energy to the grid, not just consumption - Energy produced in the regenerative mode of operation is supplied to the grid - there is no need of burning the excess energy in the braking resistor - The current on the grid side is of a pure sine wave shape, with the current THD lower than 3% Disadvantages: - Higher cost Its main advantage is in the applications, where there is a very frequent or even permanent regenerative mode of operation, where regenerated energy leads to rapid returnability of the equipment. This can be lifts, cranes, some strokes, or in general applications with speed control of induction or synchronous generators. Further opportunities are facilities with very strict requirements for current harmonic distortion like laboratories or residential zones.

The principle of soft starters is in continuous change of voltage (phase control) during acceleration (deceleration), thus limiting the current, but at a price of decreasing the motor torque. Therefore softstarters are not suitable for start up of large inertia loads and obviously not suitable for variable speed control as are the converters. VONSCH produces soft starters [SINAM 400](https://vonsch.sk/products/sinam-400/en) for 400 V motors in the range of 4-630 kW. If required, we also supply 500 Volt **SINAM 500** or 690 Volt **SINAM 690** version.

Cables heat up, voltage drops and the distributor charges penalties for reactive power consumption. **Impact:** cos φ = 0.7 means 30 % unnecessary grid load. It requires oversizing of cabling and transformers - increased investment and operating costs. **Solution:** NEXICONTROL generates compensation current precisely in antiphase - instantly. cos φ → 1.0, penalties at zero, grid stable. ## Comparison of compensation methods | Criterion | Capacitors | Passive filter | NEXICONTROL | | --- | --- | --- | --- | | Response | seconds | fixed | < 50 ms | | Harmonics | none | partial | full compensation | | Accuracy cos φ | ±0,05 | fixed | ±0,002 | | TCO | low CAPEX | medium | lowest TCO | ## Operating modes **Reactive power compensation (STATCOM)** Continuous regulation of reactive power to cos φ = 1.0 or the required setpoint. **Harmonic suppression (APF)** Active filtering of higher harmonics - current THD below 3 %. **Voltage stabilisation** Maintaining grid voltage within the permitted band even with rapid load changes. **Grid Support** DROOP regulation, island grid support and PV/battery system support. ## Models and power ratings | Model | Reactive power | Nom. current | Dimensions (WxHxD) | Weight | | --- | --- | --- | --- | --- | | [NEXICONTROL 400 050 COMP](https://vonsch.sk/products/nexicontrol/en) | 50 kVAr | 72 Arms | 400×1800×300 | ~150 kg | | [NEXICONTROL 400 100 COMP](https://vonsch.sk/products/nexicontrol-100-plus/en) | 100 kVAr | 144 Arms | 800×1800×400 | 300 kg | | [NEXICONTROL 400 150 COMP](https://vonsch.sk/products/nexicontrol-100-plus/en) | 150 kVAr | 216,5 Arms | 800×1800×400 | 300 kg | | [NEXICONTROL 400 200 COMP](https://vonsch.sk/products/nexicontrol-100-plus/en) | 200 kVAr | 289 Arms | 800×2000×400 | 320 kg | ## Active reactive power compensation system ## Control, integration and dispatching NEXICONTROL active compensators are not isolated devices - they integrate into the customer's existing infrastructure: - **Remote dispatching** - connection via industrial **EWON** router, remote access and alarm management through **Talk2m** service. - **Web visualisation** - power factor, reactive power, harmonic distortion and device status directly from the browser. - **Communication** - Modbus RTU/TCP, CAN, integration into upstream SCADA / dispatch. - **Hybrid systems** - combination of passive and active compensation, control-algorithm optimisation for specific load profiles (35+ years of VONSCH experience).

Compared to wind and solar it has incomparable advantages: ** Predictable output - water flow changes gradually. ** 24/7 supply - independent of daylight, clouds or wind. ** Lower CAPEX than wind or solar at comparable installed power. ** No farmland footprint - integrates with the landscape. ** Minimal transmission losses - generation can sit next to the consumer. ** Stabilises grid edges - even small output makes a real difference. ## How MVE CONTROL works MVE CONTROL is a **tandem of two inverters**. The first handles **generator speed control** on a water-wheel motor or turbine, extracting the maximum power from the current flow and water speed. The second - an **actively controlled regenerative inverter** - delivers that power straight to the grid with a power factor of 1. On startup the system **auto-synchronises** to both the grid and the generator. When current, frequency or grid parameters cross safety limits, the plant is **immediately disconnected** by opening the input contactor.

We are enthusiasts of modern technologies. We specialize in customer solutions for electric drives, renewable energy sources and special voltage sources, delivered to the Czech Republic, Germany, Poland, various African countries and Australia in addition to Slovakia. We believe that together we will be able to contribute to innovation and the creation of revolutionary solutions in the field of electronics. We want to make our city, region or country a better place for living together with people and for people who have the need and passion to change, to change energy. Of course, we are primarily talking about electricity, its production, distribution, storage, consumption and conversion. We believe that it pays to communicate politely and openly with our employees so that we can communicate together and equally with our business partners, because we care about mutual trust. We believe that together with our people, we can grasp top technologies and create products that bear the stamp of our 30 years of experience. A strong, balanced and relatively small team of experts and enthusiasts for progressive technologies, which we purposefully build, can create a close, highly qualified and competent bond to the technical problem, and resides under one roof. As a result, it can effectively and agilely attend to smaller projects and respond meaningfully and quickly to customer support requests. It is not possible to buy a solution for all technical problems from large international producers. Some situations require an individual specific comprehensive approach and we are here to find and offer such solutions. We are always aware of the high quality, meaningfulness and effectiveness of the solutions. ## A story that began in steel works More than 30 years ago, our fathers had experience from Slovak **steel works (Mostárne)** - they were solving motor control for **large tower cranes**. They were looking for new, innovative solutions - and in **1990** they founded VONSCH. > “30 years ago, we were unique in the development and production of frequency converters.” > “Later we started to look for new applications - we moved from large to small drives - we were ahead of the curve.” ### Today Today VONSCH offers **tailor-made power electronics solutions** - for efficient AC motor control, small hydropower plants, battery inverters, photovoltaic systems, traction drives, and **custom voltage sources** (artificial grids for various frequencies and amplitudes, tailored to specific customer needs). --- ## company/mission/en **URL:** https://vonsch.sk/company/mission/en # Mission and vision ![VONSCH R&D engineer designing an inverter](https://vonsch.sk/images/company/company_rd_1920.jpg) ## Why do we do this? We seek technical truth. Solutions that truly work. We believe that it pays to communicate politely and openly with our employees so that we can communicate together and equally with our business partners, because we care about mutual trust. We believe that together with our people, we can grasp top technologies and create products that bear the stamp of our 30 years of experience. A strong, balanced and relatively small team of experts and enthusiasts for progressive technologies, which we purposefully build, can create a close, highly qualified and competent bond to the technical problem, and resides under one roof. As a result, it can effectively and agilely attend to smaller projects and respond meaningfully and quickly to customer support requests. Not all technical problems can be solved by large international producers. Some situations require an individual specific comprehensive approach and we are here to find and offer such solutions. We are always aware of the high quality, meaningfulness and effectiveness of our solutions. ## How do we do it? In the heart of Slovakia, in the middle of the mountains, we have the opportunity to work in the top-quality environment for living, which is why it is very important to us to minimise our impact on it. That is why we carefully create solutions in the field of green energy. The results of our calculations are not aimed at artificially promoting the sale of our products, but take into account the true facts, whatever they may be. We work on improving ourselves, on improving our products and solutions in order to help realize the intentions of our customers and partners. We care about quality. All products are designed according to the strictest technical criteria in order to meet the highest expectations. We think about how to achieve a long-term perspective and a long life for our products, which is evidenced by the fact that many of our products from the 90s still work and bring benefits to their owners. We are actively building processes to maintain the high quality of our products and services. We develop our products to the stage where we can "love" them, which means that we know them perfectly, including their pluses and minuses. And when we look for employment for them, we think about making them "well", because we care about them. With balance, we create solutions in the field of green energy, for the gentle use of renewable energy sources such as the sun and water. We help shape the way we think about electricity and the future of energy, in what way it is possible to take care of our needs, the environment, the country we live in and love. ## What are we doing? The subject of our interest is electric energy and its effective management on the side of production, distribution or storage, as well as on the side of consumption in the field of electric drives. VONSCH covers a space in the global market that opens up when customers are faced with solving specific technical problems that require an individual approach from a competent, qualified team of people for whom these topics are a passion and mutual cooperation is a joy. Integration of specialized solutions in the field of drives, network inverters and other power electronics using the most modern automation elements in combination with VONSCH products, in which we know every part of the hardware and every line of software. In this way, we can create solutions that are not only standardized but also tailor-made for our customers. ## We create products and solutions usable for: ![VONSCH icons](https://vonsch.sk/images/design2026/ikony_misia_vizia.png) - control of electric drives - mining locomotive drives - photovoltaic power plants - battery energy storage systems - small hydropower plants - customer solutions for both AC and DC voltage sources ## What is VONSCH's vision for the future? To be the expert and first choice where catalogues fall short. To build and maintain a compact local environment with excellent people and conditions for the creation and development of our own products, which will enable a close, highly qualified and competent link to the technical essence of solutions in the field of power electronics. To work so that the footprint on the environment is as low as possible. Follow the principles of frugality and ecology in the entire process of our operation. We realize that building and maintaining such an environment depends mainly on quality and passionate people. That is why at VONSCH we are intensely interested in our people, in their education, improving fine skills, movement, health, building better interpersonal relationships, but of course also improving technical and computer skills, as well as cooperation with educational institutions - in the process of training experts in electrical engineering, we want to be an active regional player. To generate profit for planned goals. We are experts in our field, we maintain an excellent level of professional knowledge of our employees. Develop own VONSCH technologies and provide support to our solutions and their users. And thanks to our philosophy, products, solutions and services, the transition to renewable energy sources will become easier and more affordable for everyone. --- ## servis/en **URL:** https://vonsch.sk/servis/en # Service Warranty and post-warranty service for our entire product range.

Call-outs are normally carried out on working days from 6:00 to 16:00; other terms can be agreed within a service contract. We also advise over WhatsApp on the same line. ## Warranty repair A warranty repair is carried out either under a concluded service contract - where repairs within 24 hours or less can be agreed - or at the earliest possible date after reporting, as agreed with the customer. As a rule immediately, within 3 working days at the most. A service intervention here does not mean merely turning up for the repair, but removing the fault: the service department has its own specialists and a stock of replacement products and spare parts. Quality components and a 72-hour test of every product on a real motor or real load keep the number of service interventions low. The procedure for warranty repairs is described in the product documentation. Standard frequency converters up to and including 90 kW must be delivered to our headquarters; for higher ratings our service technician will agree the date and method with you. Every repair requires a completed [Request for repair](https://vonsch.sk/reklamacie/nova_reklamacia/en). ## Post-warranty service Post-warranty service is just as fast and available as warranty service. The customer is given options to choose from and advice stays free of charge - the root cause of a fault is very often in auxiliary equipment or in the wider technical context, not in the product that merely reports it. ## Preventive inspections and prophylactic service Preventive inspections are carried out at agreed intervals under a service contract or a contract on preventive inspections. ## Operator training By arrangement we train equipment operators, and we can also train your staff in the wider technical context. --- ## company/profile/en **URL:** https://vonsch.sk/company/profile/en ![Locomotive concept design at the whiteboard - VONSCH R&D team](https://vonsch.sk/images/company/company_concept_1920.jpg) # Company profile Addressing the most complex applications is a challenge for us... **We are a team of professionals with years of practical experience and tradition in the field of power electronics with our own research, development and production.

The interface is **bilingual (Slovak / English)**, switchable with a single click. We built VONSCH Energy Cloud so that owners of solar plants, small hydropower stations, diesel gen-sets in Fuel Save mode, battery storage and other sources don't have to log into ten different tools just to check how their plant is doing. The on-site IPC controller pushes data to us on its own - generation, power, RPM, water level, faults, anything. We store it, organise it, and show it in a way that makes sense: daily, monthly and yearly totals, 15-minute trends, hourly production, fault log. Users can export the data to CSV any time and pull it into their own reports. Who it's for - Operators of PV, hydro, BESS and hybrid (Fuel Save) systems with VONSCH technology - Energy managers and maintenance teams who want data at hand instead of a SCADA client - Plant owners who need reporting without running their own server ## What users actually do on the portal Production statistics - daily, monthly, yearly totals [![Production statistics - daily, monthly, yearly totals](https://vonsch.sk/images/energy_cloud/02_production_stats.png)](https://vonsch.sk/images/energy_cloud/02_production_stats.png) Production for **today, this month, this year, and across multiple years**. Clear bar charts with daily, monthly and yearly breakdown - see at a glance how the plant is performing. Hourly production and CSV export [![Hourly production with 15 / 30 / 60-minute configurable interval](https://vonsch.sk/images/energy_cloud/04_hourly_stats.png)](https://vonsch.sk/images/energy_cloud/04_hourly_stats.png) Hourly production with a **configurable interval of 15 / 30 / 60 minutes**. CSV export for accounting, the energy market operator or your own report. Plus fault log (when, how long) and file management for the installation. What sets it apart - Built directly for the **VONSCH IPC** - no integration tuning needed - **Bilingual interface** (SK / EN) switchable with a single click - **Secure sign-in** with a 12-hour session and an optional 180-day "remember me" - Full **REST API** for those who want to pull data into their own system - **Backup database** - if the primary DB goes down, data is written to a fallback and merged back automatically once it's healthy. No lost interval. ### Interested in VONSCH.CLOUD? We offer **VONSCH.CLOUD** on request for all relevant VONSCH applications.

Our people work on your product, under your name, and the results are yours. Three forms of engagement ## Who builds it VONSCH has been developing and manufacturing power electronics since 1990. Development, production and service are under one roof in Brezno - the same people design, commission and repair the equipment. - In-house development of hardware, firmware and control algorithms - eight experts - In-house production, commissioning and type testing - Test laboratory under the same roof - power quality analysers, oscilloscopes, spectrum analyser, thermal cameras - Service and technical support feeding directly back into R&D Seven areas - [Traction drives](https://vonsch.sk/solutions/traction/en) - [Reactive power compensation](https://vonsch.sk/solutions/reactive-power/en) - [AC drives](https://vonsch.sk/solutions/electric-drives/en) - [Photovoltaics](https://vonsch.sk/solutions/solar-energy/en) - [Battery inverters](https://vonsch.sk/solutions/battery-storage/en) - [Small hydro power plants](https://vonsch.sk/solutions/hydropower/en) - Custom voltage sources ## Turnkey custom development You give us the requirement and the operating conditions, we deliver finished equipment. Four phases - the first one decides whether the last one will make any sense. How a solution is built Phase 01 ### Requirements and analysis Operating conditions, duty cycle, standards. We separate what is a real requirement from what is just habit carried over from the previous equipment. Phase 02 ### System architecture Topology, sizing, semiconductor selection. Control behaviour is verified by simulation in MATLAB / Simulink before the first prototype is soldered. Phase 03 ### Prototype and validation Prototype, laboratory measurement. Type tests, EMC, documentation, commissioning. Phase 04 ### Serial production and service Production, commissioning, operator training. Long-term care - we commonly support equipment for more than two decades. ## What we typically build If your requirement falls inside one of these ranges, we have already built it. Outside the range we solve it case by case. | Area | Voltage | Power / current | | --- | --- | --- | | Traction drives | 80 - 1,000 V | 1.5 - 500 kW | | Artificial AC mains 50 / 60 / 400 Hz | 50 - 690 V | 1.5 - 500 kVA | | Backup supplies and UPS | 400 V | 33 - 100 kW | | Thyristor switches ACSW | 3 x 400 V | 72 - 100 A | | Traction battery chargers | max. 500 V DC | max. 20 A / module | | Industrial drives and AFE | 3 x 400 / 500 / 690 V | 0.37 - 1,400 kW | ## Real projects, real numbers Most of it exists because a catalogue solution did not work in that particular application.

Our own measuring equipment and workshop - on top of a capacity rental, you can also order measurement or a sample build. ## Development capacity rental We rent you capacity from our own development team. Our people work on your product, under your name, and the results are yours. Experts who build drives Hardware, software and electrical design are covered by eight experts. Not all of them are free. Which profiles we can assign, and from when, we agree against your requirement. 01 ### Dedicated specialist Full capacity of one profile. Your project manager directs them, they are part of your team. 02 ### Partial capacity An agreed monthly allocation, for example 40 to 80 hours. For consultations, or for a single topic. 03 ### Team with its own lead An assembled team for hardware, software and electrical design. You set the task, our lead answers for the output. ## Three things everyone asks about - **Ramp-up** The first week is not spent explaining what field weakening is, or why the current waveform changes with the modulation. Your engineer does this daily on our own products. - **Backup** You are not buying one person. When they get stuck, the colleague who has already solved it sits next to them - and behind them stand the laboratory and the production floor. - **Intellectual property** Our people work on your product, under your name. ## What we know The tools, buses and standards we have proven on our own products. ### Hardware, mechanics and electrical design Converter topologies from 0.37 kW to 1400 kW, 3 x 400 / 500 / 690 V AC, traction 80 to 1000 V DC.

Ramp-up takes days, not months. ### Solutions that run in the field Our control runs in mining locomotives in Australia and holds up island grids in Africa. Out there you do not reboot the equipment. ### Our own firmware Whatever the application needs can be programmed straight into the drive. We are not tied to anyone else's control software. ### Nearshore inside the EU The same time zone and working calendar, Slovak and English, a face-to-face meeting within a day. The results of the work on your project pass to you. ### Lifetime measured in decades We build products to last decades, not a warranty cycle. Long-term spare-parts availability and managed obsolescence. ### We name our mistakes When something goes wrong, we name it and fix it. Service and technical support run directly through the development team. ## Do you have a requirement no catalogue product covers? Send us the operating conditions and the duty cycle. An engineer will come back to you within 48 working hours with whether we can build it - and how.

Registration of intellectual property protection other than a patent [Application filed on 14 December 2014, PUV 163-2014](http://registre.indprop.gov.sk/registre/detail/popup.do?register=uv&puv_id=694144) — evidenced by the entry in the register of the Industrial Property Office of the Slovak Republic. Published on 7 January 2016 in Bulletin No. 01/2016. #### 2. Placing two new and improved (innovated) products on the market Industrial research into modern control methods aimed at improving LV distribution grid quality was closely tied to research and modelling of the optimal architecture of modern active compensation devices. The results have been and will be applied in several VONSCH products (UNIFREM, QUATROFREM, FOTO CONTROL 3f and others). The project not only led to the innovation of existing products but contributed significantly to the creation and market launch of three new products — exceeding the measurable indicator of two new products. - **[SRVS 10/230AC](https://vonsch.sk/solutions/solar-energy/en)** An electronic continuous regulator acting as an active single-phase reactive power compensator. By controlling the voltage amplitude across the compensation elements it continuously compensates single-phase reactive power. It allows any linear RLC loads or their combinations to be used to achieve the required active and reactive power characteristics, and helps cover medium- and long-term power outages. - **[GSE CONTROL 3f 400](https://vonsch.sk/products/archive/gse-control/en)** The Peak Energy Generator (inverter) is a family of modern three-phase VONSCH inverters used to cover peak demand, for example the quarter-hour maximum, and as a parallel backup source (UPS) for a 400 V three-phase supply system. Typical features include high efficiency, fast start-up, fast response to load steps, reactive power compensation of loads with an adjustable range from 0.8 capacitive to 0.8 inductive, and active higher-harmonic current compensation. The device keeps current harmonic distortion minimal even when the grid voltage is significantly distorted. When grid-connected, these inverters allow rapid disconnection through active grid-loss detection. - **Single-phase inverters [FOTO CONTROL 1f](https://vonsch.sk/products/archive/fotocontrol-1f-230375/en) with [accessories](https://vonsch.sk/solutions/solar-energy/en)** The grant significantly supported the research and development of the FOTO CONTROL 1f single-phase inverters, intended not only for photovoltaic applications. They are available in two voltage versions: FOTO CONTROL 1f 230/375 DC and FOTO CONTROL 1f 230/48 DC. They include a range of compensation functions that minimise current THD (approximately 1 % at nominal power and resistive load) and regulate reactive power across a cos φ range from -0.8 capacitive to -0.8 inductive, compensating various load types with high reactive power consumption. They also feature active anti-islanding through higher-harmonic injection, guaranteeing safe disconnection from the grid within 100 ms of a grid outage. FOTO CONTROL 1f inverters serve as a building block for both simple and highly complex single-phase and three-phase photovoltaic systems. The knowledge gained through the grant was also applied to the accessories: RM GRID MONITOR — module for measuring phase current and voltage at the node RM SYNC — module for synchronising single-phase and three-phase inverters RM WEB — module for remote monitoring and visualisation --- ## privacy/en **URL:** https://vonsch.sk/privacy/en # Privacy Policy *Last updated: May 8, 2026* This document explains how VONSCH spol. s r.o. processes personal data you provide via the request form at [vonsch.sk/request](https://vonsch.sk/request), by email, phone or any other channel as part of pre-contractual or business communication. ### 1.

A security flaw in equipment like that has physical consequences. If you have found a vulnerability in one of our products or services, we want to hear about it before anyone else does. ### Where to report **[security@vonsch.sk](mailto:security@vonsch.sk)** If you would rather not use e-mail, write to us at VONSCH spol. s r.o., Budovatelska 13, 977 03 Brezno, Slovakia. The choice of channel is yours. Machine-readable contact details: [/.well-known/security.txt](https://vonsch.sk/.well-known/security.txt) We monitor this mailbox continuously. Please do not use it for service requests, warranty claims or orders - those have their own channels and will only be delayed here. ### Scope In scope are all VONSCH products with digital elements and the services we operate: - frequency converters and inverters: NEXIFREM, UNIFREM, QUATROFREM, MVE CONTROL, NEXICONTROL, NEXIBOOST, UNIRU, PV COMP, GSE COMP, GSE CONTROL, FOTO CONTROL, - firmware and communication interfaces of those devices, - the NEXILINK remote diagnostics and connectivity layer, - control and service software: VONSCH Drive Studio, mobile applications, - online services: vonsch.sk, VONSCH Energy Cloud, VONSCH Support Center. Out of scope are third-party devices, even when deployed alongside ours; installations we do not operate; and findings with no demonstrable security impact, such as raw automated scanner output without verification. ### What to include - which product, model and firmware or software version, - what the flaw does and how to reproduce it, - the impact as you see it, - how we can reach you, and whether you want to be credited on disclosure. English or Slovak is fine. An incomplete report is better than none - we will follow up. ### What we commit to | Action | Time frame | | --- | --- | | Acknowledge receipt | within 3 business days | | First substantive response | within 10 business days | | Status update | at least every 30 days while the case is open | | Coordinated disclosure | within 90 days of the report, or sooner by agreement | If we miss one of these, we will say so and say why. We do not pay for reports and we run no bug bounty programme. If you would like it, we will credit you among those who helped us. ### What we ask of you - Test only on equipment you own or where you have the operator's consent. Our products run in other companies' plants - testing on someone else's installation is interference with their operation, not research. - Do not damage data and do not disrupt operation. No denial-of-service testing. - Do not handle personal data. If you encounter it, stop and tell us. - No social engineering against our staff or customers, and no physical access attempts. - Do not publish the finding before we have agreed a date. ### Public promise If you report a vulnerability in good faith, follow the rules in "What we ask of you" and do only what is reasonably necessary to demonstrate the flaw, VONSCH will not file a criminal complaint against you and will not bring a civil claim against you on that account. Testing of services we ourselves operate, within those limits, is authorised by us. Testing equipment at a customer site without the operator's consent is not - that is already in the rules above. If, while researching in good faith, you unintentionally exceed those limits and tell us without delay, we will take that into account. This assurance covers the conduct of VONSCH. It does not bind public authorities or third parties, such as the operators at whose sites our equipment is installed. The assurance does not apply to conduct that breaks the rules - in particular damage to data, disruption of operation, handling of personal data, social engineering, physical access to premises, or publishing the finding before we have agreed a date. We will not disclose the reporter's identity unless they ask us to or the law requires it. ### Security advisories Once a vulnerability is fixed and an update is available, we publish an advisory: what the flaw is, which devices and versions are affected, what the impact is and what the operator should do. Advisories appear on this page and on the support page of the affected product. *As of today we have no published security advisories.* ### What happens next The VONSCH security team takes over the report, assesses it, determines severity and prepares remediation. Where a vulnerability is actively exploited or an incident is severe, Regulation (EU) 2024/2847 (Cyber Resilience Act) obliges us to notify ENISA and the national CSIRT. Those deadlines run independently of our correspondence with you. *Last updated: 18 September 2026* --- ## products/unifrem-400/en **URL:** https://vonsch.sk/products/unifrem-400/en # UNIFREM 400 **UNIFREM 400 is the latest generation of frequency converters family.

These converters are often called as Active Front Ends. QUATROFREM converters allow bidirectional power exchange between distribution grid and the motor. Also, in contrast to standard frequency converters the current from the mains grid is of clean, sinusoidal shape, with configurable power factor. **QUATROFREM** reduces the biggest “disadvantage” of standard frequency converters – high harmonic current flow from supply network. **QUATROFREM** practically “gets” just first harmonic of the current, thus meeting the strict standard **EN 61000-3-12**, which any “classical” frequency converter can not meet. **QUATROFREM** ensures the recuperation of the energy to the supply grid during the regenerative operation of the motor. The most advantageous use is in the plants where frquent and energetically massive regenerative operation occurs. Compared to standard frequency converter (which turns the energy created during the regenerative mode of operation to heat of the connected brake resistor), QUATROFREM acts incomparably more economically. **Ideal applications for 4-quadrant frequency converter are lifts of the cranes and elevators.** Energetic advantages are notable in applications where dissipation of braking energy into braking resistor causes undesired heating of the surroundings. QUATROFREM is also targeted to be used in **wind power-plants**. It is also convenient to use QUATROFREM in case of request for minimization of THD, even if the energy recuperation does not occur. QUATROFREM controls the power factor (cos φ) and in comparison to other 4-quadrant converters, it allows the end user to set the desired power factor in the range of (0.95 – 1), which can compensate the capacitive currents flow in the same grid. QUATROFREM is able to keep its output voltage at nominal value even when input voltage drops by 15%. That keeps the nominal power of the drive during voltage drop or fluctuations and keeps smooth flow of motor torque. At nominal value of input voltage, QUATROFREM can increase output voltage by more than 10%, which ensures the increase of motor power by 10%. Up ## Key advantages ** ### Energy regeneration to grid Returns braking energy back to the grid instead of dissipating it in a brake resistor - energy savings in dynamic applications such as cranes, lifts and centrifuges. ** ### Sinusoidal grid current Active PWM rectifier ensures almost sinusoidal grid current with total harmonic distortion THDi below 5 %. ** ### 4-quadrant operation Full control of torque and speed in both rotation directions, suitable for dynamic applications with frequent braking and reversing. ** ### Power factor control Programmable cos φ (capacitive or inductive) enables reactive power supply for grid support and improved overall plant power factor. ** ### High efficiency Optimised power stage with modern IGBT modules - overall converter efficiency typically above 97 %. ** ### Robust protections Built-in protections against overvoltage, undervoltage, short circuit, phase loss and overheating.

RUN, FAULT, VOLTAGE PRESENT, VALVE OPEN) - Auxiliary relays - Time relays - Circuit breakers - Tempering of the enclosure - Ventilation of enclosure - the power section - Contactor of valve magnet - Service socket 230 V - Input and output terminals - Grommets - Rotary switch START ## Description of the operation of wheel motors with SHPP: **Start:** When the START switch is turned to the ON position, the main input contactor is closed. In series with the START switch contact of water level sensor that blocks INPUT switch contactor at low water, respectively. off the main contactor in the absence of water. Then, however, remains on the START switch is in the ON position, the system is therefore automatically after switching level sensor. After switching - clipped by the network can handle up to about 3 times the (must run the initialization of power electronics systems). For a specified period of current drawn from the mains only about 5% nominal current (DC controlled charging circuit) and during that time the system does not operate a network controlled inverter. **Turning of:** Switching the START selector to OFF de-energises the main INPUT CONTACTOR of the switchboard. A latching STOP push-button is wired in series with the contactor coil, so pressing STOP also drops the INPUT CONTACTOR and disconnects the unit from the grid. The STOP push-button is mounted on the switchboard, and additional STOP buttons can be wired around the SHPP. Where unauthorised use of the STOP button is a concern, or where the switchboard's location inside the SHPP makes the button unnecessary, it may be omitted from the circuit. **Flying start:** After the INPUT CONTACTOR is energised the unit is ready for operation. If the water-wheel motor is already spinning under external drive, the control electronics determine its speed without a speed sensor and set the output frequency exactly to the generator frequency - a flying-start synchronisation with the generator. Once synchronised, the power-maximising algorithm sets the most favourable supply-voltage frequency for the generator. **Maximizing the power of SHPP:** MVE CONTROL 400 includes a dedicated software feature (SHPP power maximisation) that automatically tracks the maximum available generator power by optimising both the generator speed and the voltage at the current operating point. This feature is optional and can be left disabled. **Shutdown at the low water level:** Shutdown at minimum water level is implemented by dropping the INPUT CONTACTOR. While running (input contactor closed), MVE CONTROL 400 continuously monitors the generator; if the minimum flow no longer allows generator-mode operation, the unit automatically transitions into STAND BY. **Protections:** Grid-side input protection: an overvoltage protection device is wired at the switchboard input, and the power electronics are protected by fast gR-class semiconductor fuses. Generator protection: current, power and temperature of the generator are continuously monitored by both the hardware and software of MVE CONTROL 400. **Shutdown at the failure:** On a system fault (for example a power-electronics failure) the power output of MVE CONTROL 400 is naturally blocked, and the unit attempts a restart after a configured delay. If the underlying cause has cleared (for example generator overload or a grid overvoltage), MVE CONTROL 400 resumes normal operation. During a fault the water-inlet solenoid valve is also closed. After the fault clears, or once supply voltage returns following an interruption, the water-inlet solenoid is re-opened via a time relay set to roughly 5 s. This delay is needed because the power electronics need about 3 s after re-connection to the grid to complete control-system initialisation; only after initialisation has finished may water be admitted to the water-wheel motor, at which point the automatic flying-start synchronisation can engage on the spun-up wheel. **Shutdown in case of failure of one supply phase:** MVE CONTROL 400 continuously monitors the presence of all three phases of the mains voltage at its input. During power phase loss, it immediately (within 10 ms) blocks the operation of power electronics, and MVE CONTROL 400 stops supplying power to the grid. If the loss has ended, MVE CONTROL 400 is put back into operation automatically. **Activity at limit temperatures:** The enclosure is ventilated for heat dissipation and also equipped by ventilation at temperatures below + 5 ° C. **Low temperatures:** When the temperature during turn on of the device is below + 5 ° C, condensation of water on the electronics may occur. Therefore, the enclosure is first "heated up" to a temperature of +5 ° C and then the input contactor is switched. Therefore, the heating is connected before the input contactor . **High ambient temperatures:** MVE CONTROL 400 constantly monitors the temperature of its cooler and power elements. It is designed for operation up to the ambient temperature +40 °C. At higher ambient temperature, it is necessary to reduce the power by about 1% per 1 °C. When overheated, MVE CONTROL 400 is automatically turned off. **Type of the generator:** As the generator standard induction motor can be used. Due to possible overheating check at maximum power we recommend motor with built-in temperature sensors in the windings. MVE CONTROL 400 checks the temperature of the motor and blocks its operation when overheated.

With the use of phase control, the voltage applied to the motor terminals is continuously increased and thereby continuous motor acceleration is ensured. Also, resulting from phase control and continuous decrease in terminal voltage after drive's stop command, smooth drive deceleration is ensured. Since the soft starters include microprocessor DSP control, almost linear starting up and running down of a motor can be attained resulting from motor torque modeling. Firstly, the torque is modeled by measuring values of current, voltage and motor power factor, and secondly, on required values of torque increase (decrease). The connection of a soft starter can be freely adapted to customer needs. The user can choose a standard soft starter connection in series (power supply - soft starter - motor) with the line voltage applied to the motor or a DELTA connection, where soft starter is connected inside the delta loop of a delta connected motor, controlling the voltage applied to each winding. Where the optional accessory - cooling unit - is used, bypass contactor is not required. As a result of soft starter's internal measurements of motor current in each connection, motor temperature protection is not needed. ## Contents: ![SINAM 400](https://vonsch.sk/products/images/menice/sinam400.jpg) Examples of applications: Electrical ADVANTAGES: Mechanical ADVANTAGES: Standard equipment Optional accessories Technical data General technical data User guide Technical drawings [Library for ELCAD](https://vonsch.sk/engine/download.php?dir=0&soft=TD_VON1_06_set.zip) ## Key advantages ** ### Soft motor start Gradual voltage ramp-up eliminates mechanical shocks on the motor and driven machinery and prevents grid voltage dips during start-up. ** ### Motor protection Built-in thermal and current protections, phase loss and undervoltage detection -

With the use of phase control, the voltage applied to the motor terminals is continuously increased and thereby continuous motor acceleration is ensured. Also, resulting from phase control and continuous decrease in terminal voltage at drive's switch off, smooth and controlled drive deceleration is ensured. Soft starter operating states are indicated by five LED, which are placed on the front side of soft starter enclosure. Voltage converters SINAM 400M are equipped by the circuit indicating the termination of ramp increase. This circuit is besides optical signaling equipped by contact relay output connected in the coil circuit of motor contactor. After acceleration finishes, this circuit by - passes soft starter power elements by switching on motor contactor. It means that the motor is directly connected to the power supply and therefore abnormal warming of power elements does not occur. As a result of mentioned facts the converter can be characterized by high efficiency and small dimensions. At drive running down, firstly motor contactor switches off and the soft starter smoothly decreases motor voltage to zero values, thereby the smooth drive run down is ensured.

Unlike conventional small UPS systems, they are designed for industrial three-phase applications with power ratings from 4 kW to 250 kW and are built on the current [NEXICONTROL](https://vonsch.sk/products/nexicontrol/en) inverter platform combined with [VONSCH LV battery modules](https://vonsch.sk/products/lv01-modules/en). ## Industrial series UPS (online double conversion) [![Industrial series UPS (online double conversion)](https://vonsch.sk/images/riesenia/ups17_series_web_EN.png)](https://vonsch.sk/images/riesenia/ups17_series_web_EN.png) **Online double conversion** backup power supply – power range 4 kW to 250 kW, short-term overload 2× rated current (higher on request). Energy passes through two conversions: from AC mains to DC (battery charging) and from DC back to AC for the output "artificial" grid supplying the backed-up equipment. **Pros:** - custom solution tailored to the customer's operation - any grid failure (overvoltage, undervoltage, short circuit) will not cause downtime for backed-up devices - guaranteed output voltage quality, very low voltage THD - sinusoidal grid current, THDi < 3 % - adjustable grid-side power factor (0.9 inductive to 0.9 capacitive) **Limitations:** - higher price compared to the parallel solution - inverter must be sized for the total continuous load including inrush currents ## Parallel UPS with short outages (line interactive) [![Parallel UPS with short outages (line interactive)](https://vonsch.sk/images/riesenia/ups17_paralel_web_EN.png)](https://vonsch.sk/images/riesenia/ups17_paralel_web_EN.png) Backup power supply similar to the **line interactive UPS** type – power range 4 kW to 250 kW. The device performs only **one energy conversion**: from AC mains to DC for battery charging. During a mains failure the energy flow reverses – from battery through the inverter to the loads, with the grid disconnected after outage detection. **Pros:** - custom solution tailored to the customer's operation - guaranteed supply voltage quality, very low voltage THD - sinusoidal battery charging current, THDi < 3 % - peak-shaving – injecting additional power into the load to reduce peak grid consumption - sized only to cover short-term outages - lower price and higher overall efficiency compared to the series solution **Limitations:** - certain grid faults (large overvoltage, short circuit) may cause a short outage of the backed-up equipment (under 1 s) ## Backup for Industrial Machines and Elevators [![Backup for Industrial Machines and Elevators](https://vonsch.sk/images/riesenia/bat_ups.jpg)](https://vonsch.sk/images/riesenia/bat_ups.jpg) Many applications require a backup solution to **properly terminate the operation cycle** during a power failure – typically electric trolleys, casting lines with melts, rolling mills or elevators. VONSCH [UNIFREM](https://vonsch.sk/products/unifrem-400/en) frequency converters allow emergency operation with minimal backup energy requirements. **Elevator technology** – concept of **automatic emergency run** of the cabin to the nearest floor during a mains failure. VONSCH has developed the optimised elevator backup supply **UPS‑ZZ‑325 V, 230 V / 1500 – 3000 VA** – it generates 325 V DC for the hoist drive inverter (motor 1 – 2.5 kW) and 230 V AC for the door drive, control system and brake (total up to 500 W). UNIFREM drives implement a **special function to detect the motion direction favoured by gravity** (cabin vs. counterweight) – the motor can run in regenerative mode and move passengers to the nearest station with minimal battery energy demand. ## Modern NEXICONTROL Platform Current industrial backup power supplies are built on the three-level [NEXICONTROL](https://vonsch.sk/products/nexicontrol/en) inverter platform using ANPC technology and the latest-generation Infineon® power semiconductors. Combined with [VONSCH LV](https://vonsch.sk/products/lv01-modules/en) battery modules and the [NEXISTORAGE R18](https://vonsch.sk/products/nexistorage-r18/en) rack, they form complete industrial UPS/BESS solutions with bidirectional energy flow, peak-shaving and the ability to provide grid ancillary services. **Online monitoring via VONSCH Energy Cloud [![VONSCH Energy Cloud - production stats](https://vonsch.sk/images/energy_cloud/02_production_stats.png)](https://vonsch.sk/images/energy_cloud/02_production_stats.png) For relevant VONSCH applications we offer the web portal **VONSCH.CLOUD**.

Most often it is the conversion from 230/400V 50Hz to 110V 60Hz. This device serves as **voltage** and **frequency converter**. The specific **artificial mains is custom designed to satisfy the individual requirements**, with virtually no power restrictions. Basically there are two design principles: customer enters the required parameters and the power of an artificial mains, or electrical parameters and power are designed by VONSCH engineers for specific device parameters (e.g. number and types of motors or any other electrical equipment). All components are mounted in the enclosure with all the necessary electrical equipment and signalization. ## Artificial mains for testing of the products for 60 Hz grid Product called **"ARTIFICIAL AC mains"** is offered for manufacturers of electronic devices, which are being exported to countries with other parameters of electrical grid. VONSCH Artificial AC mains is a voltage generator with a frequency of 60 Hz (or different), which is used for developing and testing the products under any supply conditions. The artificial mains is based on VONSCH power electronics. The artificial AC mains can be supplied by an European standard grid 3 x 400 V, 50 Hz. Its output voltage is adjustable to the range required by the accepted standards dealing with the grid voltage fluctuations. Output voltage is monitored by appropriate sensors, which are involved as a feedback control circuit of the output voltage, so **the output voltage reference is followed regardless of the load** value. Output frequency 60 Hz is also adjustable in the range of the required tolerances. ## "Inverse" artificial mains Quite often we address the requirements for "inverse" Artificial mains, for the ability to run equipment designed and produced in countries with 230/400V 50Hz grid conditions in other countries using other standard of mains voltage and frequency, for example 60Hz network in the Americas. Typical application is the **operation of the European machinery or other equipment in the US and Canada**. ## Other artificial mains usage VONSCH Artificial AC mains are suitable for replacement of older rotational converters and generators, which are close to their lifespan and their maintenance is costly and problematic. Artificial mains can be **designed for any other frequency** as well, e.g. **400 Hz** for testing aviation or military equipment. ## Selected references [★ ![Umelá sieť pre výrobcu potravinárskych zariadení](https://vonsch.sk/references/preview.php?w=400&foto=ZmlsZT11c3RvbXJhX3dlYjEuanBn)](https://vonsch.sk/_upload/referencie/ustomra_web1.jpg) Food and Beverage Slovakia 35 kW ### [Umelá sieť pre výrobcu potravinárskych zariadení](https://vonsch.sk/references/detail/en?id=223) Exporting to 60 Hz markets, product testing, powering special technologies or replacing rotary converters - all need a source o… ** More info [★ ![Jednofázová umelá sieť pre prevádzkovanie a testovanie výrobkov strojárskeho podniku](https://vonsch.sk/references/preview.php?w=400&foto=ZmlsZT1VU21pY2hhdGVrLmpwZw==)](https://vonsch.sk/_upload/referencie/USmichatek.jpg) Mechanical engineering Slovakia 3 kW ### [Jednofázová umelá sieť pre prevádzkovanie a testovanie výrobkov strojárskeho podniku](https://vonsch.sk/references/detail/en?id=225) Exporting to 60 Hz markets, product testing, powering special technologies or replacing rotary converters - all need a source o… ** More info [★ ![Umelá sieť pre servisnú údržbu leteckých zariadení](https://vonsch.sk/references/preview.php?w=400&foto=ZmlsZT11bWVsw6Egc2llxaUgVG9wIGNvbnRyb2wuSlBH)](https://vonsch.sk/_upload/referencie/umel%C3%A1%20sie%C5%A5%20Top%20control.JPG) Mechanical engineering Slovakia ### [Umelá sieť pre servisnú údržbu leteckých zariadení](https://vonsch.sk/references/detail/en?id=227) Exporting to 60 Hz markets, product testing, powering special technologies or replacing rotary converters - all need a source o… ** More info [★ ![Artificial AC mains AN 150kVA 1f 60Hz, 1x230VAC/1x115VAC for compressor manufacturer](https://vonsch.sk/references/preview.php?w=400&foto=ZmlsZT1VU2VtYnJhY29mcm9udF93ZWIuanBn)](https://vonsch.sk/_upload/referencie/USembracofront_web.jpg) Mechanical engineering Slovakia 150 kW ### [Artificial AC mains AN 150kVA 1f 60Hz, 1x230VAC/1x115VAC for compressor manufacturer](https://vonsch.sk/references/detail/en?id=195) Exporting to 60 Hz markets, product testing, powering special technologies or replacing rotary converters - all need a source o… ** More info [All references in category Custom power supplies →](https://vonsch.sk/references/index/en?kategoria=custom) **Online monitoring via VONSCH Energy Cloud [![VONSCH Energy Cloud - production stats](https://vonsch.sk/images/energy_cloud/02_production_stats.png)](https://vonsch.sk/images/energy_cloud/02_production_stats.png) For relevant VONSCH applications we offer the web portal **VONSCH.CLOUD**.

We never store your name, address, phone number or payment details in a cookie. ## How it works on vonsch.sk **Analytics cookies are loaded only after you consent.** Until you agree, neither Google Tag Manager nor Google Analytics is loaded - we measure nothing at all. This is not a setting we switch off afterwards: the measurement script is inserted into the page only at the moment you click *Accept all* in the banner, or enable analytics cookies in *Settings*. **The site is fully functional without consent.** Rejecting analytics cookies closes no section and no feature - inquiries, manual downloads and sign-in all work exactly the same. We remember your decision for 180 days so that we do not ask on every visit. After that period the banner appears again. ## How to change or withdraw your consent You can withdraw your consent at any time - as easily as you gave it. Open the category settings with the button below (the same *Cookie settings* link is in the footer of every page), switch analytics cookies off and save your choice. When you withdraw consent we also delete the analytics cookies already present in your browser. ## Cookie categories - **Necessary** – page session, the record of your cookie decision and sign-in to the members area. The site cannot work without them, so they cannot be switched off and the law does not require consent for them. - **Analytics** – Google Analytics 4 deployed via Google Tag Manager.

There are two exceptions: - **The map on the Contacts page** – an embedded OpenStreetMap. **It loads only after you click a button** - until you do, nothing is sent to the OpenStreetMap server. After the click your IP address is sent to them, just as visiting any website does. The map uses no advertising cookies. - **The video in the Support section** – embedded in *youtube-nocookie* mode, which prevents YouTube from storing tracking cookies unless you start the video yourself. The Facebook, LinkedIn and YouTube icons in the footer are ordinary links - clicking one takes you to that site, but merely displaying our footer sends them nothing.
