1. Products Information
1.1 Motor Soft Starter
EM-GU motor soft starter, the use of intelligent digital control; It used to various squirrel-cage asynchronous
motor control of load, the motor can smooth starting under any working conditions, protect the drag system,
reduce the starting current impact on power grid, ensure reliable motor starting. Intelligent digital motor soft start
equipment system with the complete protection function, extend the service life of the system, reduce the cost of
system cost, improve the reliability of system and compatible with all the functions of starting equipment; It is a
new ideal alternative for traditional star triangle starter and self-coupling decompression starter.
