Tripp Lite BC600SINE 600VA 375W UPS Battery Back Up Pure Sine Wave PFC Tower 120V USB, 6 Outlets Review

Updated review 10/1/2011:

Would have been 5 stars if it weren't for the strong burnt odor while new.

Good points:
(1) It works as advertised - while on battery it outputs a fair sine wave of 114 VAC RMS at 62 +/- 1.5 cycles, an enormous improvement over the coarse stepped square wave AC output of non-sine UPS's. It's pretty clean with a 35-watt load, and only somewhat distorted with a more typical 175 watt load of a single computer + LCD monitor, so even PC's with newer PFC power supplies should work OK with it (for waveform illustration I uploaded 2 scope photos to Amazon's product web page). Switchover time is acceptably fast, no blips seen on a computer.
I did not test the USB auto-shutdown software.

(2) Decisive factor in choosing this Tripp Lite: their tech support is actually located in the U.S. and gave prompt accurate answers to my questions. Another U.S. brand I contacted had overseas "support" which gave me a completely erroneous answer to a simple question; when queried again they said they would get back to me, but never did. One prays that Tripp Lite will not someday yield to the sorry practice of outsourcing support to unqualified answering services abroad.

Caveats, first 2 minor & the 3rd more major:
(1) The owner's manual is oversimplified to the point of being insulting, without such essential information as the battery type, runtime table (available online), and steps for replacing it (the battery door is locked by an unmarked screw). Their ads say "Hot-swappable, user replaceable batteries" but the manual states that "There are no user-serviceable parts inside" and "Battery replacement should be performed only by authorized service personnel". Further research shows that its single 12-volt RBC51 battery can indeed be replaced by owners, and that this excuse for a manual is likely the result of technically-illiterate legal personnel overruling the tech writers in a sad effort to avoid any kind of responsibility.

(2) Not a green machine: it runs warm, drawing 15 watts even when the battery is fully charged and nothing is connected. By comparison, a non-sine UPS of similar capacity draws only about 2 watts when not in use. If in service 24 hrs/day, the BC600SINE will add about $1.50 a month to your electric bill even while on standby.

(3) When new it gives off a very strong, unpleasant, penetrating odor like burned plastic, fumes that built up in a small computer room and greatly irritated my nose and eyes - I had to put it outside for 21 days, powered on with a fan blowing through it, before the smell decreased from being intolerable to just annoying. Googling now turns up similar complaints for other UPS makes - evidently the Chinese factories are using materials that are inferior to those of times past when manufacturing was done here. For many years I worked with electronic equipment in the military, industry, and at home, and never encountered such a long lasting bad smell except in devices that had burned up components in overloads. So, be aware that if you have a functional nose and intend to use this UPS in a small room, you might not be able to stand the odor for 3 weeks or more after delivery; on the other hand, in large well-ventilated rooms like offices it may not be so overpowering.
