I used to, for some reason, insist on using online UPS rather than standby; this led me to Intellipower:
http://www.intellipower.com/ I dunno if I ought to mention them though. We bought a number of rounds of them over a few years (from, say, 1991 through 1997). The ones we bought worked pretty well, right up until they didn't :) While they all lasted 5+ years, most of them long enough to go through more than one set of batteries, each one ended up having electronics failures eventually. I dunno if this is an issue with always having the inverter going, though; maybe somebody here knows. And battery replacement wasn't always easy. These days we are using standby units, mostly (if not entirely) APC. BTW there used to be a place over on the west side of Manchester that had a small warehouse of UPS-like stuff and who sometimes had interesting things for sale. Wish I could remember the name. mm (who has, like others, heard good things about minuteman) (or you could get one of those flywheel systems..) _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
