Running entire system through UPS.

[buffo]

Should the PC and projector be on the same UPS?

Ideally, yes. And considering that most solid state projectors don't draw more than your average computer, I'd say size your UPS so that it will run two desktop comptuers and you'll be fine.

any UPS will run a computer and laser...
The question is FOR HOW LONG?

i have 750VA model running my Photoshop computer + A3PRINTER + NAS
when the circuitbreaker goes down..the system runs for 18min before power runs out.
In that time te system has shut itself down properly..

You guys want to run the UPS as a filter for "pollution" and voltage spikes etc.
I cant imagine a 750 or 1000 UPS won't cut it for a moderate solidstate laser system.

I am more interested in the clean power that the battery back up. Is there a filter or something that can be used instead of a UPS?

Yes, but you must be careful and get the correct one, and they still do not protect against under/overvoltage, and not against all spikes, delta with a sting, or lifted grounds. Avoid MOVs (Metal oxide varisters), MOVs have a finite lifetiome

A key concept is that the whole system including audio might have to run off the UPS in some cases.

The pro audio guys usually have nice boxes for this, or get a Sola transformer.

I like to put these on units, only usually the more massive 10 pound ones:

You can find units these power conditioner units that actually have no significant solid state electronics and they deal with noise spikes brown out overvoltage etc, most are very heavy units I have three of these I use these in addition to several 2200 watt APC UPS and have never had issue with any blown or damaged equipment or down time. I used to be in the business of processing insurance lightning and surge damage claims, and swear by the stuff,well that and being a Journeyman Electrician.

Not quite. If you have a 350VA UPS and you put a 700VA load on it, it will not carry the load.

However, so long as you're within the load limit of the UPS (or only *slightly* over it) you should be fine.

I cant imagine a 750 or 1000 UPS won't cut it for a moderate solidstate laser system.

Right. But a 750VA UPS will easily run 2 computers. A 350VA unit will not. Which is why I mentioned that you can't just buy the cheapest UPS you find and expect it to work. You need something with a little grunt... (Because your average solid state projector draws about the same power as a standard desktop PC, so in effect you need enough juice to power 2 PC's.)

I was thinking a while back of running the whole projector off of a car battery (regulating down to the correct voltages needed.) The battery would be on the floor under the projector table. That could power the reds, the green, the galvo amps. The only thing that has to have 115vac is the LaserWave blue and there's probably a way around that, or a small inverter. A medium size car battery should be around 60AH (thats not CCA) @ 12V so that should run 4 amps for an evening or 2.. ~ 15 hours or so before re-charge. I dont have a lap-top, but don't those have a 12V input for portable use in the car if needed (when the internal batt is low)? That could be be powered from the car battery too.
