Product Details



Product Description:

This soft start motor starter is a new type of starting equipment. Equipped  with the international advanced level design, our product is produced by power electronics technology, micro-processing technology and modern control theory. It effectively reduces the starting current of the motor in order to avoid the investment in grid capacity increase. It makes the motor control technology adapt to the higher requirements of the rapidly developing power automation technology. What's more, this soft start motor starter can be widely used in loads such as fans, pumps, conveyors and compressors. It is an ideal replacement for traditional pressure equipment, such as delta conversion, auto-coupled buck and magnetically controlled buck.


Product Feature:

This soft start motor starter helps to reduce the starting stress of the motor and load equipment and  extends the service life of the related equipment.

Equipped with perfect and reliable protection functions, our product is able to  protect the safety of the  production equipment.

The soft stop function effectively solves the parking surge problem of the inertia system.

It can effectively limit the starting current of the asynchronous motor when it is started.
