CK70 Built-In Bypass Soft Starter Use DSP Central Processing Unit


CK70 Built-In Bypass Soft Starter 440V soft starter
CK70 series intelligent soft starter with built-in bypass is a brand-new product optimized and launched on the basis of our CK60 economic soft starter.
Based on the CK60 economic soft starter, the CK70 series is a brand-new product optimized and launched, and its overall performance has been greatly improved to become the preferred product for high-performance drive control of general machinery.
It has become the preferred product for high-performance drive control of general-purpose machinery. The product adopts today's international advanced level of power electronics technology and microprocessor
power electronics technology and microprocessor technology, and adopts high-performance DSP as the central processor to ensure the real-time, superior

Principle of operation

By limiting the starting current and starting torque, the soft starter can reliably prevent mechanical shock and voltage drop in the power grid during the starting process. The motor starting voltage is reduced by controlling the SCR conduction angle, and the motor starting voltage is increased to the rated voltage within the set starting time. By virtue of this stepless control of the motor voltage, the motor can be adjusted according to the load characteristics of the driven machine, gently accelerating the machinery and equipment, thus significantly improving the operating performance of the machinery and equipment, as well as the voltage drop of the driven machine.
This significantly improves the operational performance of the machine, reduces maintenance costs and extends service life.
