Vector control frequency inverter
This frequency inverter supplied by our factory integrated vector control function. This inverter can continuous running even if power supply off for a few seconds, this new feature allows the motor running automatically in unstable electric power supply environment, plus, it can track the induction motor's speed in real time and start at its current speed when the power supply on, this feature makes the electric motor work more smoothly with less maintenance. Also, this frequency inverter adopts the most popular technical features, like PID control, Modbus RS 485 communication etc.
