Marhynchus Variable Frequency Inverter 2.2KW VFD Single Phase 110V to Three Phase 220V Spindle Motor Speed Control Frequency Converter

The instruction sheet wasn't the best, but the VFD works fine so far!

I just made a 110v extension cord and hiked this up before I used this for my big ass fan. All I needed to to was change the four program lines in each code from 50hz to 60hz. I tested this vfd with my fluke and it does produce 220vac three phase. I now have it running my 20’ fan. The dynamic brake in the vfd works well also! I can’t talk about how long this will last. But I’m amazed how easy it was to hook up and it actually works. I’m going to buy a lotto ticket today for sure!

The manufacture’s instruction/documentation leaves a lot to the imagination and trial and error. The hardware does what it is designed to do.

This is the second order. First one got mishandled somehow, got completely wrong item in the correct labeled box! Seller was great and took care of it without any issues. Now about this 110V input VFD. Runs and drives 1.5HP 3Phase 230V Baldor motor really well. No change in settings of any kind, stop/start forward/reverse drives the motor without load just fine. Documentation is primitive at best, but no big deal. There are plenty on-line if one wants to tinker with settings. Time will tell the quality in the long run.

Great way to create a soft start on smaller horsepower motors. We changed our 1.5HP single phase pump motors to 3 phase so we could use an inverter to control ramp speed and eliminate high inrush current at startup. These drive work very well for our application. Easy to program and pretty self explanatory instructions.
