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.
