Soft starter main components Is a three-phase parallel crystal connected in series between the power source and the controlled motor Brake AC voltage regulator. Change the firing angle of the thyristor Adjust the output voltage of the thyristor voltage regulator circuit. Throughout the start During the process, the output of the soft starter is a smooth boost Process (and can have current limiting function) until the thyristor is fully turned on, The motor operates at rated voltage.
Motors with soft starter start-up have the following advantages over direct start-up
1 Reduce the grid voltage drop caused by the startup process
2 Reduce the inrush current during motor starting
3 Reduce the wear and impact of the transmission mechanism
