I've got a quite expensive LCD monitor (~$1000) and I wish to protect it from instabilities in the power line. So I intend to get a UPS for it.
I see two types of UPS devices which differ on the output waveform - it's either a stepped approximation to a sinewave or a pure sinewave (rather expensive SmartUPS series). I've heard stories that some devices are intolerable to a non-pure sinewave and their power units just burn out for some reason.
Can anybody tell me whether it's a good idea to attach an expensive designer monitor to such a UPS with non-sine output or better grab a more expensive one which generates a pure sinewave?
Most UPS makers say to not attach a laser printer. I believe they have huge start-up power demands - presumably due to the need to heat up the fusing roller to it's operating temperature as fast as possible. An LCD monitor will have very low and consistent power needs. Visitor may just need a surge suppressor. – RedGrittyBrick – 2011-01-20T14:45:33.337
@RedGrittyBrick, Well, the laser printer was just an example of why it's important to check the power consumption. I didn't say that you should attach laser printers to an UPS. Even if you acquire a "Surge suppressor / filter" you need to check the power consumption. That and the UPS being overkill, was my point. – Max Kielland – 2011-01-20T15:09:16.847
