AC Soft Starter kW can work with three-phase AC motor in the process of starting too big acceleration torque, and power supply system plays a protection from excessive current harvest dynamic impact role,
Through controlling the conductive angle of three phase anti-parallel thyristor that is connected in series between power supply and the controlled motor. AC Soft Starter 75kW make the terminal voltage of motor rise to the rated voltage from the preset value. Reaching the aim of smooth starting by reducing current during the starting process. It belongs to the category of reduced-voltage starting. Hence. Starting torque would be reduced somewhat. It is suitable for locations where are not strict with starting torque. In order to obtain the optimum efficiency of AC Soft Starter
