Reduce the starting current of the motor, reduce the di-stribution capacity, and avoid investment in capacity ex-pansion;
Reduce starting stress and extend the service life of motors and related equipment;
Smooth start and soft stop avoid the surge problem and water hammer effect of traditional starting equipment;
A variety of starting modes and a wide range of current and voltage settings, can adapt to a variety of load occ-asions, improve the process;
Improve the reliable protection function, more effective-ly protect the safety of the motor and related equipment;
Can be used for frequent start and stop The occasion.
