Variable frequency drive

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.


Power range: 0.4kW to 2.2kW for 1 phase 220V
0.75kW to 500kW for 3 phase 380V
Input voltage: 200V - 240V, 380V - 440V ± 15%
Output voltage: 0 - input voltage
1) Sensorless vector control model variable frequency drive
2) Wide range input voltage
3) Stable operation in unstable power supply area, continuous running automatically in instantaneous electricity power off
4) Track electric motor speed in real time to avoid shock impact to the motor
