The 7000 I had ran a 48vdc fan at horrid amps.
Once the AC was input, it ran to 48vdc, and then
modules dropped it here and there to other
voltages.

I was thinking there was some wierd 3 phase in
it, but when I got the machine disassembled, it
was all DC at 48v.  The use of 110vac power
supplies and 48vdc internally without any 3
phase in actuality, should make conversion to
home power relatively simple.
