Purpose:
Mainly applicable for the control and protection of the starting and stopping of squirrel cage asynchronous and synchronous motors. It uses high-quality series connected thyristors to continuously control the output voltage, ensuring smooth starting and stopping of the motor. It has fault protection functions such as overload, phase loss, and peak overcurrent during starting. Using it can effectively avoid harmful impacts on the power grid caused by excessive starting current of the motor, and can use high-power motors normally and extend their service life under limited power grid capacity.
1) Reduce the starting current of the motor, decrease the distribution capacity, and avoid investment in capacity expansion;
2) Reduce starting stress and extend the service life of electric motors and related equipment;
3) Smooth starting and soft stopping avoid the surge and water hammer effects of traditional starting equipment;
4) Multiple starting modes and wide range of current, voltage, and other settings can adapt to various load conditions;
5) Improve reliable protection functions to more effectively protect the safety of motors and related equipment.
Technical features:
Multiple starting methods
Voltage linear curve starting, voltage exponential curve starting, current linear curve starting, current exponential curve starting. And programmable jump starting torque and starting current limits can be applied in each mode. The unique basic algorithm makes the motor start and stop more accurate and smooth.
