These are the heavy duty units similiar to the ones I had a several years ago.
Replace the batteries and they should be good for 3-4 years, filtering line
spikes, dips, and providing clean A/C power up to 15 minutes at full rated
output. These ARE NOT like those cheap UPS units that the computer shops push.
All UPS units will require battery replacement. I have a source of batteries
in Marietta with lower prices.
qty 2 - APC 450 VA @ $20 each
qty 1 - APC 600VA @ $25
qty 1 - Compaq 1920VA $75
The 1.92KVA unit comes with an external 48V 40A DC power pack (in a similar
case) along with the connecting cable. This one's impressive!
I can bring them to the upcoming NFARL or SEDXC meeting, but prefer a Roswell
pickup.
