Finding the right UPS! I need some help!

I'm sorry if this is in the wrong section... I poked around but could not find a better place to ask this. By all means, please move or delete this if need be.

I've decided that after spending over $3,000 on a nice television, I'd like to protect it with a UPS, rather then just a surge protector. I've found plenty of information reguarding UPS's in reference to computers, but no information as to what the minimum reccomendation would be for buying a UPS to protect my Sony LCD 55" Grand Vega!

Any shoves in the right direction in terms of a good value would be appreciated. I'm sure some of you out there found a good deal on one that would protect my little setup (xbox, dvd player, tv)... so please help a guy out!

At the very least... what level of wattage protection should I get at the minimum for a home theatre setup?

My RPCRT 50" requires 300 watts. I use a OptiUPS 800C. It is rated at 800VA.


Add up your watts available on the nameplate for all of your equipment and divide by .8 for the minimum VA rating. More VA will allow for longer backup.

Thanks for the info :)

In case I decide to rely on my Circut City warrenty (and I guess homeowners insurence, in a worst case senario) and only buy a surge suppressor...

Can someone link me (or tell me the model of) just a simple surge suppressor that is going to be better then the home depot $1.03 brown variety, but not overkill? I want something more then the standard surge protector, but also don't want to waste money.

Any comments are welcome!

What happened to the UPS?


The best place to shop for UPS or surge protectors is a computer store like MicroCenter. The appliance orentented stores like BB, CC and Sears are fine for TVs, but not so good for some accessories. More surge protectors and UPS units are sold by the computer stores, so they know more about them.

Look for a Tripplite Isobar surge protector, but you would be better off with the UPS. A UPS will allow for you to turn off your DLP when there is a power failure, but still have power to the set to allow for lamp cool down. Something a surge protector can't do.

Yep, wouldn't give up on the UPS, we had a really
ugly power outage where I live last week, Transformer
on the pole blew up, but it was a very dirty outage, spiking and
browning for almost 1 min before it finally died. Others in the area
lost CRT tv's and other valuble electronics but my Sammy didn't
even flinch on its UPS, I was able to turn it off and let it cool down
no problem, AS far As I am concerned My UPS Just saved Me a
possible very large expence, probably a new lamp at the very least..

I suppose for a moment I lost sight of the big picture and tried to pinch pennies after spending thousands of dollars on the nicest television I've ever had the pleasure to sit in front of. I claim temperary insanity, I suppose.

So far everything I've seen about UPS's has been for computers. I was trying to stay out of retail stores (I have a compromised immune system due to cancer treatment) and while I -can- go out and shop, I try to avoid it as people stare at the teenager with a walker and mask on. Is there a place online that sells items like the OptiUPS 800C cheaply, or should I plan on making a trip to a computer chain? I suppose I could always Ebay- but I wish someone would spoon feed me the model UPS I should be buying ;)

I'm just always second guessing that I'm looking at an overkill item, and then I worry that what I pick up instead will be el-cheapo and not enough! ARG!

Anyway, thanks guys.

Much appreciated! Thanks for getting that info to me- I assume you agree that the OptiUPS 800C will work for my setup as well, so I'll just get that one and that's that!

Do I really need a UPS that's rated for all my equipment, or just the TV? Can't I just use a surge protector for the rest of the stuff?

Also, do all RP sets need the cool down time, or just the CRT's?

Actually the CRTs don't need it, it is the TV that use a lamp like the DLPs, LCOS and LCD rear projection. And of course all projectors. They have cooling fans for the lamps that need to stay on after the TV is turned off.


Yes you can use just a surge protector for the other stuff. Audio amplifiers, etc. My Opti has 3 surge protected outlets and 3 UPS outlets and I use the surge protection outlets for some of my stuff. I do use the UPS outlets for the satellite receivers and the VCR. It keeps the satellite receivers from having to reboot on short power outages, which takes several minutes for the Tivo unit. It keeps the clock set on the VCR.

How good is the surge suppression on the Opti that you have? Is it strong enough to take a lightning strike? I've been hearing conflicting reports about the possibility of -anything- really stopping a direct lightning strike... including rumors of the local firehouse having a trashed electronic's setup when they were running several $400 UPS units... but I was just wondering about the basic protection on the Opti. Is it a good surge supressor first, and then it adds the battery as a bonus? Or was it built to run through brown outs, and the surge fuses were added as an afterthought?

For some reason I've become hung up on trying to find "the best" power supply possible for my precious new television, so please excuse the almost OCD nature with which I'm asking questions about a UPS of all things. :)

Hmm, hadn't really thought of the convenience factor there. Thanks for the tip. :)

One more question: Does this act as a line conditioner as well? How necessary is a line conditioner? (maybe it was two questions :rolleyes: )

I can't find a kVa reading ANYWHERE on either the sony website, or in my sony manual to try to figure out for -sure- which UPS would work best for me.

I just wanted to check that the OptiUPS 800C would *for sure* protect my Sony KDF-55WF655. I feel so helpless not being able to find such basic info, anywhere!! Can someone either assure me that it'll be fine with that UPS, or let me know what I need to upgrade to? Does it change that I would also want to plug in my DVD player and Xbox into the battery outlets? I could always just put them on the surge part if it is a problem, and not worry about giving them battery backup.

I wish a UPS was made for HT specifically and not always for computers- it makes me less confident buying one... I feel like I'm using it for the wrong purpose!

And SesnOfWthr, I'm fairly sure UPS's act as line conditioners as well, as most boast about brown out protection, and protection against irregularity in current.

There is not anything, short of unplugging, that will protect from a direct lightning strike. The best you can do is protect from surges caused by lightning out on the power grid. If you get a strike on the pole feeding your house and the lightning decides that your equipment is the least path of resistance to ground, that's where it will go.


Does this act as a line conditioner as well? How necessary is a line conditioner?
As far as the UPS being a power conditioner, it does that job very well. The output voltage is supplied by an inverter that receives its power from the internal battery, so it is somewhat immune to waht's going on on the power line side. The battery is kept charged by a built in battery charger. It provides just about the best isolation from your power line as is possible. I don't think you can do too good a job of line conditioning. I feel it is very necessary.

The Opti 800C will provide about 640 watts of continous power (@80% power factor) which should be plenty for your TV and the DVD player. I'd suspect your TV would require less power than my CRT RP TV and it takes 300W. Another way to look at it is a normal household 15 amp circuit will supply about 1440 watts of continous power, so the Opti800 is roughly half that amount.

There should be a data sticker on the rear of your TV that will state the power requirements. If it is stated in amps multiply by 120 to get watts.
