An AC soft starter is a device used to control the starting and stopping process of an AC motor. It realizes smooth starting by gradually increasing the voltage to the motor and reduces the current shock during starting, thus reducing the load on the motor and the power grid. Soft starters help extend the life of the motor, reduce mechanical wear and improve the overall efficiency of the system. It is widely used in pumps, fans, compressors and other high-power equipment that require smooth starting.
