Huanyang VFD CNC Variable Frequency Drive Converter Controller 1 phase 220v input 380v 3 phase output 2.2kw 3hp Inverter for Motor Speed Control

First of all, I have to say how pleased I was with the speed of the shipment. Although they advertised that I would get it within a month, I ended up getting it in just 4 days from China. I recently purchased an old metal lathe that has a motor that runs on 420 V (first time I've seen that) and needed an inverter that could power it up. This inverter did the job just fine. The only glitch I ran into is that it is rated at 380v and if I run the lathe at the highest speed, it trips the inverter. Obviously not the fault of the inverter. It was easy enough to program, the information of how to program it was all in the manual. You will need to know particular information about the motor you plan to connect to it, such as it's input power in kW (there is a formula to convert from horsepower to kW), voltage (in volts), current (in amps), frequency (in hertz) and speed (in rpm). There may be a couple other parameters that are needed to program it correctly but like I said it was easy enough. I'm very happy with my purchase. Now let us see how it holds up in the long run. I will try to give an update in a few months (if I remember ;)

I use these to run 220v 3-phase motors with 220v single phase supply, they've been running for 2 years without problem. I will continue to buy more in the future, very happy with them.
