Hi, We have a need for a few 208V UPS in the 4-6kVA capacity range. I the past, I've used one small UPS powering a couple machines, so this is a step up in scale. Does anybody have insight into purchasing and managing these units? Our room power is generator backed, but for utility electrical outages the UPS needs to ride-out the several second generator startup time (and then the switch back to utility power). In the case of some other failure, we need time to cleanly shutdown filesystems and turnoff machines (a few minutes). The UPSs don't need long run times, I'm figuring we need 5 minutes at full load and will double this to allow for battery degradation. We're not trying to insure uninterrupted availability, just data integrity with clean shutdowns. I'm looking at 3 Tripp-lite Smart Online 208V 6kVA units each with a single external battery pack. The units will plug into our 208V 30A outlets and a single switched PDU will be plugged into each UPS to connect computers. Does anyone have an opinion on the different UPS brands? APC seems to be a bit more expensive than Tripp-lite --- is it worth it? What about service contracts, how long and what fraction of the UPS price have you paid for them? Where are you buying these, I have a quote from Dell that seems ok. Thanks, Tom Rockwell
