To place an order, please provide product model, specification, load and application condition.
Special note:
If client needs keyboard box to be externally placed, it is necessary to order the mounting accessoriess from manufacturer. When keyboard box is externally placed, it needs to lock the mounting fittings of external keyboard box onto door panel with its hole size of 115.5(H) * 104.2(W). For specific installation steps, please refer to
Soft starter is a motor control device that integrates motor soft start, soft stop and various protection functions. It is connected in series between the power supply and the controlled motor.
When the soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on, and the motor works on the mechanical characteristics of the rated voltage to achieve smooth starting, reduce starting current, and avoid starting overcurrent tripping.
When the motor reaches the rated speed, the start-up process ends. The soft starter automatically replaces the thyristor that has completed the task with a bypass contactor, and provides rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor, prolong the service life of the soft starter, improve its working efficiency, and prevent the power grid from harmonic pollution.
The soft starter also provides a soft stop function. The soft stop is the opposite of the soft start process. The voltage gradually decreases and the speed gradually drops to zero to avoid the torque shock caused by the free stop.
