Advanced digital controled close-loop technologies, and power-electronic components, 6kV and 10kV, 200A and 400A.

Introduction

QBRG series Explosion-Proof HV Soft-Starter, and QKRG series normal Mine-Used HV Soft-Starter produced by KAICHENG, uses Digital Close Loop technology, to control the thyrister output voltage, smoothly startup the motor, once the motor achieve the full load, control is switched to internal bypass contactor, and the motor operation is still monitored and protected by the Soft-Starter.

Application

The product is used in the site of Coal Mines, Iron Ore, Non-Ferrous, Petro-Chemical, Military Industry, and Pharmacy, where have the hazardous explosive environment.
