The CMC-MX built-in bypass motor soft starter is an intelligent asynchronous motor soft starter based on a trigger closed-loop algorithm for voltage regulation and current limiting. Power electronic circuit detection and advanced closed-loop control algorithms enable starting and protection functions. The built-in bypass contactor contacts utilize a magnetic latching contactor, differing from other external bypass AC contactors that operate under long-term electrification. This product is noise-free, free from electromagnetic pollution, spark-free, and environmentally friendly.
