1.Application

GSRQ1 series motor soft starter product is suitable for AC 50Hz,rated operational voltage respectively for 380V,690V,rated insulation voltage is 690V, motor power from 7.5kw to 630kw three phase asynchronous squirrel-cage motor starting and protection.Widely used in pumps,fans,conveying and compressor etc load occasion. It relieves the motor start and stop brought current surge impact on power grid,can be more effective buffer to electric machanical damage,prolong service life of motor and meet various load different starting ways and requirements. The friendly human-computer interaction interface.LCD liquid crystal chinese character display.

Can realize stall, undervoltage,lack of phase,thyristor overheating protection,start and operation thermal overload protection function. The whole monitoring current and load parameters,with motor comprehensive protection function.

2.Adopt standard and authentication situation

The products conform to standard GB14048.6 and IEC60947-4-2;

Acquired CCC certification;

3.Operating principle

It mainly consists of three phase AC voltage regulation and control circuit.It basic principle is the voltage regulation circuit using thyristor phase shift control principle,through control conduction angle of the thyristor,change its output voltage,through pressure regulating mode to control starting curent and starting torque;control circuit according to schedule different starting mode,through testing feedback current of main circuit and control its output voltage,prevent motor happen surge phenomenon.
