Main fucntions and features

It makes use of voltage-reducing function of auto-transformer, reduce the starting current of the motor. Accelerating the motor close to the rated speed ensures the normal operation of the motor and reduces the impact of the motor starting current on the transmission network. Power line with overload, under voltage and phase failure protection, and artificially disconnected motor.
