For sale is a MITSUBISHI FREQROL FR-u120-0.75K 1HP VFD VARIABLE FREQUENCY DRIVE 220v. used takeout. I believe that it works, though I have not tested it. I cannot help but notice that only two input wires (R and S) are connected, which makes me believe that it was used in a SINGLE PHASE configuration. If you do not like this item for any reason, within 7 days of receipt, you can return it to me for a refund of your winning bid. You will have to pay shipping both ways and pack carefully.
