CK70 Built-In Bypass Soft Starter uses DSP Central Processing Unit technology, representing an optimized and enhanced version of our CK60 economic soft starter. This advanced product has become the preferred choice for high-performance drive control of general machinery.
By limiting the starting current and torque, the soft starter reliably prevents mechanical shock and voltage drops during startup. It reduces motor starting voltage through SCR conduction angle control, gradually increasing to rated voltage within the set starting time. This stepless control allows adjustment according to load characteristics, gently accelerating equipment to significantly improve operational performance while reducing maintenance costs and extending service life.
