Perfect motors protection
SSR soft starter Combine the perfect protection function, It can deal with the abnormal state of electric power grid or motor, the powerful adaptability would ensure the stable operation.
Perfect pump control function
SSR have many special functions to improve efficiency, for example the Continuous torque control for the pump.
The built-in bypass
All range Bypass built in, save time, lower consume. The start and the stop process of SSR motor soft starter with consume. when the motor operation at rated speed, the soft starter triggered bypass relay, so it would save the transistor heating and save energy consume. The bypass circuit is strictly screened and tested, help customer save the wiring and installation & check time. Meanwhile it will minimize the cabinet.
Non contact start/stop motor control
The start and the stop process of SSR softstarter with smooth current change and non surge close and non arcing break. Greatly prolongs the service life of the equipment.
