    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.

    Soft Starter Works with a Bypass Contactor

    Soft starter works with a bypass contactor saving energy by eliminating thyristor losses during the run. The bypass contactor shunts the current flowing through the soft starter switch circuit to reduce heat accumulation in the soft starter power electronics during motor operation. This provides maximum efficiency and prolongs the life of soft-start switching components because they only work during the start and stop cycles of the motor.

    25hp soft starter has a certain range of tolerances
    I want to order your 25hp soft starter, but the lowest voltage shown at your website input voltage option is 220 volts. The power here measures 208 volts across the legs?

    Ok, select 220V input and proceed ordering, we shall modify your order to 208V based on sending us an email. And in all cases no worries the soft starter has +/- 15% tolerance, so also 220V will work good.
