    Anyone recomend a cheaply priced UPS for projector use only. It would only need to keep the projector going for about five minutes to give a chance to power it down.


    Thanks

    Forgot to mention that I do keep a fan plugged in beside the projector when it is running. At least in the event of a powercut this will help to cool down the projector and perhaps reduce the chances of permenent damage

    I would have thought a PJ power consumption would drain a cheap UPS very quickly!!!!

    From what I have read elsewhere, you will need one that can do a pure sinewave output - the ones with a stepped appoximation could do some serious damage to your PSU. As far as I understand, what you really need is a power conditioner, which removes nasties from the mains, to give some nice clean power to your PJ. A good example of a UPS that can condition your power would be:
    http://www.ebuyer.com/customer/prod...wcm9kdWN0X3NwZWNpZmljYXRpb25z&product_uid=459
    Or if you only want to condition your power, and dont want the battery:
    http://www.dabs.com/uk/productView.htm?quicklinx=DRQ

    Apparently, a power outage wont hurt your bulb, so long as you let it cool down again after it has turned off - so conditioning is all that can help with bulb life. Apologies for not linking to the threads where I have read about this!

    what exactly does the conditioner do beyond removing high frequency noise and dc components?

    Read Comer's post & never spotted that. Either Comer didn't realise or he's engaged in a bit of "wee" taking.

    Last I heard Comer was seen sourcing 20x 12v lead acid batteries from local car dismantlers :D

    Sorry, I thought everybody would have been aware that all fans in Ireland are sold with their own UPS.

    :smashin:

    Back to the point of the thread: It would seen that I'm going to need to spend quite alot on a system that would be good enough for a projector. I can get a new lamp/bulb for less than €300 and in all the years I've been watching movies on projectors I've only ever had only one powercut.

    Also there seems to be quite alot of debate regarding the actual damage caused by a powercut to the lamp of a projector
