UPS Question

[Sea bass]

Hi, I purchased a new 1200VA 780w UPS. I have a Phillips 704 or 708 DVR. How long will the Tivo, on by itself possibly recording last before the battery fails? Another question, I have a Sony Vega, 32". How long would UPS last with the DVR and Tivo on together? It would be kinda cool watching TV with the power out! Any help is appreciated.

The manual for my R10 says the power requirement is 40 watts. If you put your dvr all by itself on the UPS - nothing else at all - I'd guess you might get a half hour out of it.
-
Your TV probably runs 5 times that - 200 watts (or more). Add that to the circuit, and you will probably cut your battery time down to maybe 10 minutes.
-
I'm really just guessing. Take a 50 or 100 watt lightbulb, plug it into your UPS (after the battery has had time to fully charge) and see how long it lasts. That will tell you roughly how long the dvr will last.
-
Small consumer rated UPS' are meant to cover you for short term power outages, or to give you enough time to do a gracefull shutdown of equipment for longer power outages.

Do NOT hook your TV to a UPS... You will suck the life out of it, even with just general usage... TV's draw WAY too much power for the UPS.

With that size UPS.. you should easily get multiple HOURS of life, as I have a smaller one for my server PC and I get a good hour on it's life and it is easily drawing 4 to 5 times the power my TiVo is.

Thanks to all of you!

The current issue of HDTVetc. has an article on Home Theater UPS units. If you purchase one specifically for hometheater there is no proplem hooking up your television to it, this is what the are designed for. This is a formula to help determine the UPS which will fit your needs, I got this from the article;
To determine current or amperage draw do the following: Divide wall voltage into the total wattage used by equipment which will equal amps. Or if you know your amperage multiply that by the voltage to find total wattage.
