We do promise that all materials have passed the military-grade standards.
It has various perfect protection functions such as phase loss protection and over current protection during starting up.
This electric motor soft start control can be operated from a distance.
There are a variety of start terminal options can be activated through various kinds of modes.
This electric motor soft start control adopts multiple microprocessors to work. Equipped with multi-point electrical isolation design, it is available to harsh working environment. Besides, it has strong anti-interference ability and strong corrosion resistance. This electric motor soft start control has excellent internal microprocessor, it is able to calculate the optimal soft start time according to the different power of the motor. There are several digital tubes display for real-time display of operating voltage and current, which is quite flexible. At the same time, it requires quickly at any time during the rapid sampling of the voltage and current during the start up process.
