installed in the rack. AFAIK (in the US at least), there are no 220v
power controllers. You'll have either a 120v at 30A power controller or
a 3-phase power controller (but that's likely to be only for the
largest 11's - like an 11/70). Most everything else is single phase.
FWIW, I've seen 120/240V split-phase DEC PDUs, and have them still, but
I'm not 100% sure that they weren't modified 120V single phase ones. I
think they were used with some systems that had 240V powered Trident
disk drives. I don't remember excatly what model, but some model of
861 PDU sounds about right.
