Soft Start Device for High Voltage Electric Motors UBPVD-K for Smooth Starting

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: <ul> <li>- multi-motor with alternate starting of up to three electric motors;</li> <li>single-motor with built-in bypass switch or contactor.</li> </ul>The device is designed for operation in conditions of macroclimatic regions with moderate and cold climate in closed heated premises or block-modular buildings of outdoor installation with microclimate maintenance system.
