CNCTOPBAOS 4KW 220V VFD Inverter Variable Frequency Drive Converter Driver Controller 5HP 3-Phase Output 18A VSD with 2m Cable for Spindle Motor Drive Control/CNC Router Engraving Milling Machine

Works great, the occasional time I go to run it gives me an error but I reset it and it works great!Use it for my forklift charger 3ph.

The product was used and damaged. It did not work whatsoever. We had to pay our electrician ALL day to try and get this equipment running just to find out it was a bad piece of equipment. Amazon will refund us for the bad product but no one can refund us for our electrical bill which is around $400. We are out a ton of money; I would not buy ANYTHING From this seller!

Really disliked the rubber wire keepers at the bottom of the box I had to fabricate something more secure. The electronics seem to be working well It's doing what I bought it for. Decided to take a chance and save hundreds of dollars on an American brand named VFD that is most likely also made in China. The instructions and wiring diagrams are not half bad. No VFD is easy to program and install but if you stick with it and watch a few you tube videos you'll get the hang of it. I'll let you know how it goes long term after it's been in service for awhile. Have not run it under load yet. I bought the 5HP version to soft start a 3HP motor from a on off switch, nothing too complex, although the box is complex enough to set up and program any which you can think of.

Great VFD, the only thing I dislike is that the cooling fan is always on which is annoying but livable. It would be five stars if the fan only kicked on when the unit was heating up.

Like the easy operation. Programing was difficult. Used on metal lathe.
