Mining explosion-proof AC vacuum soft starter

The device adopts MX2 intelligent drive box, the latest technology developed by the United States BENSHAW, as the core. It can make the motor start in a controlled and smooth way, which is a good solution to the impact to the the grid and mechanical equipment when the motor starts, and extends the service life of the device. The device with the functions of perfect protection and intelligent communication, can be widely used in the coal mine industry to control the tape conveyor, fans, pumps and other motors.
