I have a Benq W2000 projector and would like to get an UPS for it.
I allready have an UPS rated 800VA/480W which does not work properly. If (with charged battery) I unplug the UPS's mains while the PJ is off and I start it up the UPS is fine for a few minutes. It beeps rapidly, which the manual indicates as overload, after which it looses power and beeps continuously, manual claims Faulty UPS.
However if I unplug the mains while the PJ is ON, I instantly loose power and the unit beeps continuously.
I tested a monitor, was fine, beeped every 10 seconds indicating it was on battery.
I tested the PC unit, beeped every 10 seconds and lost power after about 4 minutes (beeped continuously).
I unplugged the UPS main for both of these while running and were fine.
I assume it's because the PJ is more demaning(?). The PJ lamp has 240w, and the estimated consumption according the benq website is 353w.
What model should I get?
