VFD 3KW 4HP 220V 1 or 3 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle

Installed on a 5 hp 3 ph air compressor motor. Working great

It worked for a while but would not restart where you left off when you took power off.Now all of a sudden it just flashes numbers and does nothing.The manufacturer is always out to lunch. No support from them or Amazon.Stay away if you need a product that works in a production environment.

got the 5hp unit to run my 3ph 5hp compressor since my home shop doesn't have 3ph. manual is terrible but there are so few settings its not too bad to figure out, however once the belts were tight it started immediatly over currenting trying to run my load. even with loose slipping belts it was extreemly sensitive to the settings on the unit to run it even at lower power.

The media could not be loaded. I converted a 220/460v 3ph compressor to 220v single phase. The drive worked great. The motor is 7.5 HP with nameplate amps of 19A. The drive had no problem starting the motor and my gut is the motor is wired in star not delta. As the application is pretty simple programming the drive was relatively straightforward. The additional information listed in the product description was very helpful. The instruction manual is pretty basic. Without some drive programming experience the manual would be challenging to understand. Overall, I would recommend this drive to anyone looking for an affordable solution to convert a 3ph motor to single phase.

The media could not be loaded. I use this to add a 2nd and 3rd phase to be able to run my 3 phase air compressor. I reached out to their support before I bought it and they were very helpful. They wanted a picture of the data plate from the motor and had their engineers review to recommend which size I should get. I mentioned to them that it was for an air compressor and they even provided instructions to set it up to work with my pressure switch! I would highly recommend this VFD if you only have single phase and want to run a 3 phase motor.(Ignore my wiring. I tried another VFD first and ran 10/3 with a 30A breaker. When I switched to this one I ran 8/3 (you can use 8/2 though) with a 40A breaker. I just haven't tidied it up yet. )

Like it,fairly easy to install. Works well

I bought the units to use on a Lathe and one for a saw and mill. They have run them as stated and all my items are 3/phase and had to convert them and I am running them now.

Unit had worked fine up until I went to push the run button and had a nice ear deafening flash bang right in front of my face.
