By using the Control Panel (optional internal or external panel by switch) frequency and direction of motor rotation of each revolving stage either for all connected motors simultaneously or individually for each stage can be controlled. Reached frequency and direction is indicated by LEDs on the panel and the system can be safely shut down using the CENTRAL STOP button. Enclosure is made with a b…

Enclosure for technological line of folding boxes has an installed frequency converter for control line drive and frequency converter drive for unloading lines. The vibrator loader on the line is controlled by the original single-phase frequency converter. The control system in the control cabinet controls the operation of the entire line. It processes information from the actuator limit switches…

The device can supply the electricity to the grid even during a minimum flow of water, with high quality of current: (cos φ = -1, the current THD 5%). The device is equipped with an emergency electro-hydraulic. The generator is connected to the screw turbine via a gear. The level of the water is detected by an ultrasonic level sensor and locks level are automatically controlled by DC drives. DC dr…

Cooling system with pressure regulation, two independent circuits.

FOTO CONTROL 1f 230/375 DC inverter is used as an electronic MPPT controller of AC coil power. This solution increases the energy yield by 30-40% comparing to the standard switch.

The need to reduce the cost of the house and feed the electricity surplus into the grid, the need for remote monitoring of the inverter + status messages over e-mail was addressed as follows: Inverter FOTO CONTROL 230 / 375 DC operates in on-grid mode. RM WEB module is used for the monitoring of the power plant.

The single-phase photovoltaic hybrid system with the household consumption covering feature was installed. In case of power failure and sufficient battery capacity, the plant is able to backup the appliances in the one phase – inverter instantaneously and smoothly enters off-grid mode.

Artificial mains is used for compressor testing. Single phase AC output voltage is sensed by special measuring circuit which is connected as a feedback in output voltage control circuit. The output voltage setpoint is kept regardless of the load value. Desired voltage at the output is tuned by potentiometer within a specified range. Output AC voltage, current and frequency is displayed on the digi…

Vector control of torque and speed, converter is commanded over MODBUS RTU from PLC SIMATIC S7-1200. System is remotely monitored over eWON industrial router.

Converter with built-process PID controller regulates the pressure in the system to the desired value. At zero water intakes converter turns off automatically to save electricity. When the pressure drops below the preset value, converter is automatically started and begins pumping to increase the pressure.
