Gozuk Soft starter application scope
It is used from the soft start, speed regulation and energy-saving operation of slip ring motors with rated voltage of 380v ~15kv

Soft starter working principles       
As for motors with loads such as air blower fans or pumps, speed regulation and energy saving can be achieved by changing resistance value of the variable liquid  resistor that is connected in series to the rotor circuit of motor: the less resistance, the faster speed; the motor reaches its full speed when the resistance value reaches zero.
A heat circulation system is devised to circulate the liquid so as to prevent the temperature of the liquid from excessive rise. A central control unit can be adopted to realize remote monitoring and operation. It features its convenient control panels, convenient operations and high reliability.
