Nick As Doug said, the APC UPSes handle a very wide range of input voltage with no trouble. I used to be on a campus with 208V power everywhere, but now I'm off-campus where 120V and 240V are the norm.
My office is in a commercial leased space in a residential area, so we use a SmartUPS 3000 with the 240V input to power our rack, which expects 208V power. The rack PDUs handle the 120V side for the servers. I had a nice chat with APC tech support about the input and outputs before we bought it, and the UPS is quite capable of handling the various voltages. NOTE: Also, you may need to set the input sensors not to call 240V a spike and alarm or switch to battery. I think our unit came with the widest sensitivity, but I've had units from the factory with the narrowest sensitivity set. Enjoy the new toy!
