Hi Ron,
Just chiming in...information only.
For small VFDs (maybe some larger ones?) one can get a 115vac 1-phase input & 220v 3-phase output. I have one in my shop. Again, a small unit.
Kind regards,
DBN

Hey Nick,
Tree is a good brand. To me, the 480V is a deal killer unless it can be
rewired for 240. VFDs are nice, but I have never seen one output more
voltage than was input. Doesn't mean there isn't one, just make sure
before you base a buy decision on it.
The motor may be proprietary, so swapping it may be a problem. Again,
verify it.
Patience will save you money and usually get you a better machine.
