Bought this to try it, It was a low price, I have a Fobco Star drill with A three Phase motor, and I wanted to power it with 240v power. I rewired the motor To delta 240V , I had to change the setting from 400HZ to 50HZ and the motor starts and runs perfect , It is best to read the whole manual as there are a lot of setting that you can change. I bought the 1.5KW unit and it powered an old 0.33BHP / 0.25KW motor with no problems
