The 11/750 (mine) runs off a single 30Amp/110V supply, and the
disk drive/tape off a second 30Amp/110V supply.

Most of the internals of the 11/780 run off 12Amp/110V plugs
that are tapped off the three phases of input power in a
psuedo ballanced arrangement. There is a 25VDC (unregulated)
supply that runs off all three phase together to power the
contacters, airflow switches, etc... When I get mine into
the basement, I'll put in a 25V supply that runs off 110,
and rewire the whole rack to run off a 240VAC/60A service.

I assume the 725 and 730 run on 110VAC as well...
