Harold:
Sorry that I confused you and I am sure,
many others. Why not call APC at
1-800-800-4272 and ask for a brochure.
I am sure that their explanation will clear up the
confusion. You could also go to their web site
at www.apc.com
I believe that any computer that draws power from
an AC line should have one of these units protecting
it from power loss, whether it is momentary or long
term. They provide temporary power for saving any
work in progress on the computer when the AC line
power fails. Some of the units provide a program
that will automatically do this for you when a power
failure is detected.
I was particularly impressed with the unit's ability to
"self start" and provide power under isolated conditions.
Then they become a portable power source.
