Tips: Soft starter application fields
The soft starter can effectively limit the starting current of AC asynchronous motor, and can be widely used in fans, water pumps, transportation, compressor and other loads. It is the ideal replacement product of traditional star-delta conversion, self-couple decrease-voltage, and magnetic-control decrease-voltage equipment. AC motor soft starter has a very good energy saving effect. It uses a thyristor to reduce voltage, the power factor is low when the soft start load is light, and the soft starter can improve the power factor by reducing the control voltage, in order to achieve light load energy saving effect. The fans, pumps and other load starting torque is low, the torque will increase with the speed. When using the soft start mode can reduce the inrush starting current well, and in the shutdown we can use soft-stop to avoid water hammer effect. When you need to reduce the exciting current, you can change the effective value of the output voltage, so to achieve the purpose of adjusting the speed, while improving the system power factor, achieving optimizing the energy saving effect.
