Power back-up for projectors? - Blu-ray Forum

Grevlin · 05-06-2009, 04:24 PM

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

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.

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.
