Well, sometimes. Read the specs for your prospective UPS very carefully. "Consumer grade" units (ie. cheap ones that are generally used with PCs / comparatively low draw equipment) can vary wildly in exactly what you're getting, with not much upfront warning. "The Big Print Giveth, the Small Print Taketh Away" can apply in spades to cheaper UPSs. Some don't do any power conditioning at all and simply swap to batteries when the power goes out, while some will run you through the rectifier at all times. The first option often comes with an exciting subsecond glitch while the unit recognises there is no power and switches to battery (short, but long enough to take gear down). The other route may provide protection against peaks, but not against brownouts, or it may provide both. Read carefully and spend wisely. Not that I've ever seen anyone caught out by buying a cheap(ish) UPS and not getting the protection they thought they were getting ... As an aside, what are US domestic outlets rated for ? In the UK, I think an outlet is generally rated for 3 kilowatts, so you can run a fairly extensive set of gear off a single socket so long as you don't do anything too daft, like endless daisy chains of four-bars ... - Tony Sean Echevarria <sean.loop@creepingfog.com> wrote: >Yeah - there was an article in a recent EM - I don't remember what the >article was about but I do remember the recommendation that a UPS is >better >than something like a standard power condition.
