What is variable frequency drive?
Variable frequency drive, or VFD in short, is an AC drive that controls AC motor by changing the working power input frequency. The VFD is a kind of variable speed drive (VFD), that can adjust speed by controlling frequency. The advantages of variable frequency drive are controlling speed, saving energy, protecting the motor, and process control.
Other names of variable frequency drive: frequency converter, frequency inverter, variable speed controllers.
USFULL manufactures variable frequency drive ranging from 1hp to 840hp (630kW).
There are 2 voltage levels for VFD: 220V and 380V. 220V VFD drives include single phase VFD and three phase 220V VFD; 380V VFD drive supports input voltage up to 480V.
VFD Application Scenarios
USFULL VFD is widely used in fan, pump and textile machines. We suggest to expand power size for heavy load application such as ball mill, roots blower, crusher etc. As for compressor, injection molding machine, we have specific solutions for you.
USFULL VFD has a new design to ensure large air channel for heat sink.
Triple-proof paint protected PCB board
