Online Type Intelligent Soft Starter Cabinet with Cooling System

Intelligent ac motor soft starter is a new type of motor starting equipment designed and produced by using power electronic technology, microprocessor technology and modern control theory. The product can effectively limit the starting current of asynchronous motor, can be widely used in fan, water pump, conveying and compressor load, is the traditional star / triangle conversion, self-coupling, magnetic control and other step-down starting equipment ideal replacement products.

The concept of online is to continue to run through the thyristor after the start of the thyristor is completed. the online operation through the thyristor requires the heat dissipation of the fan, and the accompanying pipe pressure drop of the thyristor is constantly generating heat energy, which requires more electricity.

  • Model RSTZ-S
  • Power Cabinet 22KW-630KW

Feature

1.Compact structure: saves installation space, integrated design;
