I want to install a Backup UPS to ensure that my projector shuts down and cools off properly if and when the power goes out during a movie. Any recommendations to which UPS would work. I have looked at a bunch from APCC.com

Thanks

I'd say something by APC, in the ~1000 VA range would be a good choice. It doesn't need any fancy features, because your projector won't be able to tell it when to shut off anyway.

Get ready for all the "you need sine-wave UPS" posts ;)

If you insist on a UPS, all you need is one that will send line voltage when deactivated, and switches over to battery only when the power goes out.

BUT, I'm not convinced you need a UPS to begin with. Cutting power to your PJ does nothing to harm it. The harm comes in trying to cut it back on with a hot bulb. My Panasonic 75u remembers the last state, and will actually power back up in the cooldown mode before reigniting the bulb. As long as you don't try to power down/up with a hot bulb, IMHO, your money is better spent towards a conditioner/surge protector. Of course a quality UPS can do the above also, so if you're dead set on a UPS find one that does all three jobs :)

IMHO, the best UPS ive ever used is the BEST Micro FerrUPS. It uses lead-acid battery and have isolation transformer, but are large and expensive.

That said, I use only Isobar or better surge protection on my AV stuff. And you should use surge protectors even with the ups, to help protect it.
