The USPD asynchronous motor driver is designed to reduce the starting currents of an asynchronous electric motor due to the smooth supply of mains voltage to the motor windings.
Reducing the starting currents allows you to avoid a ”drawdown” of the mains voltage, reduce the load on power cables, increase the service life of mechanical equipment due to shockless start-up and braking. ZVEL-MOTOR is available for engines with power from 15 to 110 kW, operating from a standard AC network. USPD is a mounted for installation inside special box for supporting requiring air and moisture conditions. On the front panel of which there are control buttons and a liquid crystal display for initial parameter setting
