Does anyone use A UPS to protect their Projector?

Hi - I live in a semi-rural area which has overhead power cables and whether related or not, frequent power cuts. Sometimes these last literally a few seconds, others from 30 minutes to 4 hours and worst case so far has been 4 days.

On a number of occasions my £5k projector has been on and therefore not been able to go into standby and allow the lamp to cool properly.

Any experiences of using a UPS with short-term battery backup and if so, what brands, models etc? Moving is not an option!

Cheers.

I also live in a rural area with overhead power line so, yes, I use UPS's for computer and projector.

APC come highly recommended, expensive but if it saves wrecking a £300 lamp... :lesson:

That's useful - any particular model you'd recommend? The PJ has a power rating of 390W. A UPS would only be used for this so lots of additional outputs would just be redundant.

Mine are 10 years old and so obsolete, but just look at the APC website and choose something suitable.

Of course, other makes are available...

There was another UPS/ Projector thread earlier that may give some more information.
Ah - thank you.

In the meantime, I think my take-aways from this so far are:

1. A UPS is probably a worthwhile investment.
2. A silently operating one is important.
3. A sine wave output is desirable but perhaps not absolutely essential?
4. An awareness of the risks of existing battery technology
5. A budget of about £300 should be sufficient, and avoid the cheapo Chinese ones (common sense anyway I guess)

I have a Sony VPL-VW270ES and a bulb replacement is in the order of £300 as well. It currently is powered from an newly installed 13A ceiling socket and as such is permanently in stand by - I wonder if I should invest in a remote switch to fully turn off the PJ but also the UPS when not in use? Then may reduce any fire risk?

I live in a seni-rural area with overhead powerlines too. We occasionally get little blips where the power dips or cuts out for a second which could adversely affect projectors and the like. I have all my computers and servers on various UPS's which I would say are pretty essential for 'always on' PC's. For my projector I have a power inspired AG500 (I think?) which has a battery backup built in which ma be an option for you? I was going to go for another APC UPS like my PC's but read somewhere that the power output of them is a stepped sine wave (or something like that?... I can't remember the details) and when power is cut may not be the best for a PJ? The power inspired unit is an AC regenerator which may offer a cleaner mains signal if its a bit rubbish or variable coming in from the wall if you are in a rural setting? I am sure an APC unit will be fine but just thought I would offer you another option, I think it may be a bit more expensive though?

Anyway hope that helps, and you get some form of protection for the projector.

Cheers

Thanks for the input - some seem described as just sine wave, which turn out to simulated or stepped, where as others as "true sine wave" - these latter ones do seem to be at a premium price point and that's what I currently looking into - seems difficult to find something suitable as I plan to use the UPS in a dedicated cinema room, and just for the projector, so I don't need the expense of umpteen outputs. The rest of the kit is protected by an old but effective surge protector and power smoother, but no battery backup.
Looks like Cyberpower/APC and Riello are the manufacturers to look at.
