4kw 5.5 Kw 45kw 20kw 380V Soft Starter For Home Ac Unit Ck60 Built-In Bypass

With over a decade of application experience and market research, Ackwell has developed the CK60 series - a new generation of built-in bypass economic soft starters featuring improved efficiency and easier installation. Designed to meet international and domestic market demands, these soft starters provide reliable motor control solutions.

The CK60 soft starter limits starting current and torque to prevent mechanical shock and voltage drops. By controlling thyristor conduction angles, it gradually increases motor voltage to rated levels within set time parameters. This stepless voltage control allows precise acceleration matching to load characteristics, significantly improving equipment performance while reducing maintenance costs and extending service life.
