    Tips: The difference between soft starter and variable frequency drive (VFD)
    From the application, the soft starter and variable frequency drive (VFD) are two completely different products. The soft starter is actually a device that controls the voltage and limits the starting current, uses for starting motor and only changes the output voltage amplitude without changing the frequency. And VFD is used for the device needed speed governing, the output not only changes the voltage but also changes the frequency. From the function, VFD has all the functions of the soft starter, so it can be said that VFD is a more powerful soft starter.
    Although the soft starter solves the problem of motor starting, but there is no significant energy saving effect. When start using energy-saving operation mode, no-load energy saving is 40%, and load energy saving is only 5%. VFD not only solves the big impact current caused by the motor starting, but also has the good energy saving effect and the frequency conversion ability.

    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.

    Excellent soft starter
    This 30 hp soft starter has been used for a while. Easy for installation, and my motor starts up smoothly after using it. No longer have to worry about circuit breaker tripping.

    power source and your certificate
    1. The power support from Emergency generator, when motor stop but motor inertia rotation still ongoing in this time the motor like a small generator power source to the soft start device, in this case is there any effect to the emergency generator? or can damage soft starter?
    2. what certificate of your soft starter device do you have? please list all of them and send to me.

    ATO Responded
    1. It will not affect the generator, nor will it affect the soft start.
    2. There is CE certification, etc., please contact us by email before the detailed information.
