Product Introduction

The CMC-LX series motor soft starter is a new type of motor starting and protection device that combines power electronics technology, microprocessors, and automatic control. It allows for smooth, step-less starting and stopping of motors, avoiding mechanical and electrical shocks caused by traditional starting methods such as direct-on-line, ∆/Y starting, and autotransformer starting. It effectively reduces starting current and distribution capacity, helping to avoid the need for capacity expansion investments. Additionally, the CMC-LX series soft starter integrates a current transformer, eliminating the need for external connections.

Suitable power range: 7.5-530 kW.
