I appear to have become the victim of my own hastiness. I picked up an APC 3000VA 208V UPS (DLA3000RMT2U) with the corresponding 208v->120v transformer (SURT005) for $200 from a guy on Craigslist. Being in a hurry to get home, I missed the fact that these are _208v_ when I looked up the units on APC's website. If my electrical knowledge serves me right this is two legs off commercial 3-phase service voltage.

Obviously I do not have three phase in my home, where these were going to be used, so my question is this... have any of you had experience running 208v equipment on 240v single-phase mains (most likely using a buck autotransformer)? If so, do you have suggestions on where to get an appropriate autotransformer?

My other option is to just turn around and re-sell these things to someone who could use them on 208v; or swap with someone for a 120 or 240V unit of a similar capacity (moving your server room to commercial power?). I'm in the Seattle area of Washington state, in the unlikely chance someone wanted units like these.
