A UPC? Is that a uninterrupted power conditioner or something? If it's a wall wart, it's not uninterrupted, perhaps I misunderstand you.
What I described above looks like a large power bar/surge supressor. It has an actual battery built in that stays charged, and in the even of a power outage, the battery circuit provides 120v so a projector can stay running and it's fan keeps removing the heat. You can safely shut off the projector until power comes back on to the other components and you can resume your movie.
I also have a wall wart style surge suppressor for the treadmill. A great idea for surge suppression and it works just fine, but it can't provide any power to a projector should the power fail. In that case, the projector would immediately shut off, and the bulb heat inside does not get removed.
Sorry for the long explanation! So my UPS(uninterrupted power supply) unit sits out of site, and I ran an extension from it up into the ceiling over to my projector so it's protected from power failure and power surges too. Hopefully others can chime in although it seems Audiogon has few members with home theaters.
