Product Description

Introduction

high voltage auto-transformer soft starter (hereinafter referred to as soft starter) is a c designed with up-to-date concept,and mainly applicable to the control of and protection for the starting and stopping of both star and delta connected motors. In this method, the starting current is limited by using a three-phase autotransformer to reduce the initial stator applied voltage.

.he starter is composed of several thyristor in series-parallel,and it can meet different current and voltage requirements.  
 
The Product is widely used in electric industry with rated voltage 3000 to 10000 V, building materials, chemical industry, metallurgy, steel and paper-making industries etc.. And can perform well if used together with various kinds of electromechanical devices including water pumps,fans,compressors, crashes, agitators and conveyer belt etc..It is the ideal device for starting and protecting high voltage motors.
