CK70 Built-In Bypass Soft Starter uses DSP Central Processing Unit technology, representing an optimized version of our CK60 economic soft starter with significantly improved performance for high-performance drive control of general machinery.
The soft starter limits starting current and torque to prevent mechanical shock and power grid voltage drops. It reduces motor starting voltage via SCR conduction angle control, gradually increasing to rated voltage within set time. This stepless control enables gentle acceleration tailored to load characteristics, improving operational performance while reducing maintenance costs and extending equipment lifespan.
