I don't think APC makes one that size :-)
Actually they do. APC makes UPSes up to the multiple megawatt range.
There's an IBM 1401 restoration project at the Computer History Museum.
They have a German 1401, so they need to convert the line frequency from
60 Hz to 50 Hz to run it. I was surprised to learn that rotary
converters (i.e., motor-generators) have much higher MTBF that static
inverters (all-electronic).
