4HP 3kw 14A 220-250V Variable Frequency Drive Inverter VFD

This VFD can be used for constant torque loads ( such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. The inpute for this VFD is 1 or 3 phase as you like. You can control the different speed as you like when yo use this VFD. Many customer bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps & Conveyors, etc and then performance excellently. This item use Sine wave PWN(SPWM ) for the control system and performace excellently.

NOTE
Only for light-load motors, can not be used for heavy-duty motors.
