Variable frequency drive

The variable frequency drive is special magnetic flux sensorless vector control mode, with detachable LCD/LED keypads & compact design for easy installation in different environment; Modbus-RTU RS-485 communication function; Automatic running continuous while power off in a certain time and tracking the motor speed in real time to start it at the same speed & direction, to protect the AC motor from current shock impact. It's the valued drives in Low Voltage (LV) applications for AC motor speed control to save electricity energy.
