Description
Soft Starter
Soft starter is the thyristor of the main circuit at the start and stop of the motor that adjusts the magnitude of the voltage appropriately to the motor, thereby limiting the flow of power when the motor is started to improve the stability of the surrounding electrical equipment and to avoid excessive mechanical shock. It also alleviates excessive mechanical shock.
