Much of what used to be power-hungry connectivity hardware for me has gone low-power, so I'm scaling back my UPS setup some.
I've got an Elgar IPS1100, nominally rated at 1KVA sine-wave continuous (9.2A 60 Hz 120VAC). It's a pretty good-sized UPS, with fan cooling. It takes 48V in SLA cells (has an internal shelf for 8 6V 12AH ones), but I've always run it from 4 garden-tractor batteries. It's pretty good-sized; about 12"x13"x15" and heavy (big transformer). Made in 1990, has 6 AC receptacles on the back along with an RS-232 connector for status notification. Back in the day, this was a pretty high-end unit; manufacture date is 05/90. Yours for shipping; batteries not included. --Chuck
