HPVFV inverter, using high-performance digital signal processor and optimizing control algorithm,  provides fans and pumps etc with high speed ,flexible, safety control.

Including V/F control, field orientation vector control , Sensorless Vector control (this control can effectively improve the problem speed along with the change of load). PID function and auto tuning function are more suitable for fans and pumps to realize better energy saving.

System startup or reaching set value, through the S-Curve function, can realize smooth change of speed, so as to improve the large inertia load control functions.
