The device of compact design with digital control system and built-in controller, with rated output voltage of 10 kV, with rated current of 250 A is designed for soft start of high-voltage synchronous and asynchronous electric motors (EM) of compressors, fans, pumps and other units with "fan" characteristic.
The device allows to change the voltage supplied to the electric motor by phase control of thyristors of the power converter.
The device is available in two versions:
- multi-motor with alternate starting of up to three electric motors;
- single-motor with built-in bypass switch or contactor.
