What ever this thing is, it is too small for a 10 HP motor. Most manufacturers make single phase input, 3 phase output drives, but usually only up to 3 to 5 HP. A 10 HP 1PH to 3 PH could be made by some company that I am not aware of, but I would think that it would be very pricey. I would never buy a used drive. You have no idea what problems that you are getting.
I looked this device up on the MFR web site: This is an electronic single to three phase converter for up to 7.5 HP. You would need the next larger size phase converter for a 10 HP motor, AND A 10 HP VFD.
