Product Overview

SJR3-3000 series of soft starters integrated with built-in bypass can greatly reduce the construction cost in its application. 

It is different from the troubleshooting for conventional external installation and wiring maintenance and also different from the contradiction of the heating phenomena of the controllable silicon of the online soft starter.

This series also supports bus function of Modbus protocol to support large-scale industrial layout. LCD screen display is more convenient for use.

Product Features

(1) Easy to control: support a variety of communication protocols; operation panel can be used outside ; programmable output; 4-20mA DC analog output.

(2) Long life:compared to intense heating, heavy harmonic pollution and high module consumption caused by online module,  this type of soft starter has a longer using life and more safety.

(3) Liquid crystal display: this display is more intuitive and convenient.

(4): No need for control circuitry: it greatly slashes the material cost.

(5) Space saving: compared with star-delta starter and self coupling decompression starter, the built-in bypass greatly reduces space requirement for the cabinet, so the user can arrange the electrical equipment in higher density, thereby reducing the cost.

(6) Labor saving: compared with star-delta starter and self coupling decompression starter, greatly cut down the design and installation time for no need of deploying line circuitry.
