Power back-up for projectors?

[Grevlin]

Does anyone use a power back-up (battery supply) with their projector? The idea would be to have it keep the projector on during a power outage to allow you to power it down regularly and not click on and off as the power comes and goes...

a lot of people here use an ups. i do. i dont have a projector though but a ups is mainly used in case of an outage you can shut down your system safely but not use it since the battery doesnt last that long when components are being used. a ups can supply power to keep any fans going to proper cool down your compenents if needed.

It's recommended as an abrupt shutdown could damage the bulb.

Battery back-up power supply = $200
Replacement Bulb = $300-400

[Grevlin]

That's exactly what I was thinking. The power supplies usually give you 10-15 minutes, but you would be sitting in the room anyway to get up and power it down.

Depend on how much power outtage you have. I don't have a UPS because we generally miss power 1 time per Year max. When it happen, i let it cool down for 30 minutes witch is plently enought for the bulb to cool off gradually. What you don't want to do is turn it back on as soon as the power come back... Theorically you should do the same thing with a CRT (let it cool down between Power On and OFF) but i never did. Altought i do with my projector when power outtage occurs with is very rare.

Could be usefull in the thunderstorm season, but i turn off everything when a thunderstorm is near..

I only use surge protection on mine. I also do not have power outages very often so I do not feel it is a problem.

I run a UPS on my projector (Optoma HD80). It does not have a large current draw and the UPS allows it enough time for the fan to run its 90 seconds and power down properly. I have a 1500VA Ups that I got from Costco for around $100, does the trick.

Curious, does a UPS (or at least the battery portion) need to be replaced every year or so?

i have an APC for the projector and ir/rf module of the remote that way i can still turn off the pj with the remote.

I've got an APC that is over 8 years old and is still on the first battery.

Dang. To live where you do. Here in South Florida it's once a month, and maybe a brief one once every 2 weeks or so during the summer. Bad ones every month over the summer.

I also have an APC battery back-up for my Panny 3000, and it had to kick-in once already. The real issue is making sure you have power to run the FAN after a power outage, otherwise the heat from the uncooled bulb could do damage to the machine.

So yeah, get one.

for those with projectors and RPTV you should have a UPS for them. the two big reasons are one, in a loss of power the excessive heat is bad for the bulb and is bad for the internals around the bulb. two, the fan running cools the bulb to a temperature that will help prevent condensation on the bulb. both conditions could compromise the bulb's intended life span (shortening it) and may lead to viloent failure of the bulb when the time comes. for those with projectors i recommend using this system to send UPS power up to your ceiling mounted projector; it's called the powerbridge in wall power kits. click on this link and select from any of the options given that will work for you and for your in wall a/v solutions too. protect your projectors and RPTV's, think about the cost of lamps!

A DIY alternative to that is to place two regular wall outlets connected by Romex - one on the ceiling by the projector and the other behind your rack (or where your UPS lives) and connect the projector to the ceiling outlet - then connect the UPS to the wall outlet with a male-to-male jumper (connect to the wall first, then to the UPS to avoid a shock). The M2M jumper can be made easily by cutting off the female end of a power cable and adding a male 3-prong plug from a hardware store.

It's basically the same concept as the Powerbridge kit without the relatively large pricetag (and nifty cable outlet plate).

I would strongly recommend not doing this. the power bridge power inlet has been designed to meet code standards and this method, while it will most likely work, can be dangerous and WILL NOT meet code. which would void your insurance if it were to cause a fire.

I plan on using a heavy duty extension cord run along the ceiling and down the wall covered with those flat wire tracks. (Along with the HDMI cable) Then painted to match the dark color going in my new dedicated HT room. That extension cord will go into the power back-up.

-- This avoids putting in-wall lines and plugs. (And electrician bills)

I just prefer doing it myself, and I don't want to mess with code and in-wall electrical.

I'm considering this UPS:

With ONLY the projector plugged into it - Panny AE3000

Any reviews?

[Ethenolas]

I just bought a

APC SUA1500

It is "pure sine wave" which is what you want.

It is "line interactive", which is second best...

True "online" ups are the best, but will run about 1K.

The difference is online ups run everything off the battery at perfect 120V 60hz. Line interactive monitors voltage continuously and jumps in with battery if there is a problem.

Both the one listed above are not recommended for AV equipement. They are strickly designed for Computers. APC has designed equipement specifically designed to protect projectors, and other home theater equipement:

I personally recommend the J or if you can afford it S Type Conditioner with Battery.

You can do it but its not what APC designed the equipement for therefore no guaranties. In other words, if the UPS above doesn't protect your equipement it ain't APC's fault. Read the fine print.

But logically speaking I think that buying the 1500 should be aok for the projector, but only the projector. DO NOT use it for any other HT equipement.

On a side note, I was thinking about getting the 1500 myself, but haven't thrown caution to the wind yet.

[vega2K]

I came across this unit. Anyone familar? I read reviews and it is recommended specifically for Projector power-downs. The price is as low as $190 via Amazon Marketplace and about $229+ via Best Buy or Buy.com.
