Precise network on the spot:Artificial AC mains AN 150kVA 1f 60Hz, 1x230VAC/1x115VAC for compressor manufacturer
Customer challenge
VONSCH solution - turnkey
The compressor manufacturer in the Slovak Republic has had to solve the problem of testing its products for markets with 60Hz frequency. Based on its requirements, a special aingle-phase artificial AC mains was designed and manufactured to test hermetic compressors and condensing units. Output alternating single-phase voltage is measured by a special measuring circuit which is connected as a feedback in the output voltage control circuit and therefore the setpoint of the output voltage is maintained regardless of the load value. The generated grid voltage at the output of the grid is fine tuned by the potentiometer within a specified range. The output AC voltage and current of each output branch is displayed on the digital displays.
