>>ran some pull-the-plug tests on my APC Back-UPS Pro
This isn't a direct response, but this post prompted me
to answer a question raised earlier as to overloading
an APC 600 with my two PCs.
According to APC charts and manuals (and web site), I
did not overload it with both PCs
(and both monitors) running. This is necessarily vague,
as they and I are speaking estimates, guesses, config
adjustments due to inexact matches, and, no doubt,
marketing hype.
One of these days I'm going to take the trouble
to put an ammeter on the power cord under the same load
to find out. Then, naturally, I will apply the .71
power factor we learned about in the last boring lesson
to figure the UPS size in VA <g>.
In addition, according to APC's test to verify you're not
overloaded, namely, pull the plug and see if the overload
relay pops, again negative. Ran for several minutes; how many
I posted at the time but now forget -- 5 or 6 I think. I
did NOT continue the test till the point of failure but rather
shut it off when fast beeps began. APC says this is the 1
minute warning, but now that I read this post I recall in
my earlier tests it was more like a 3 - 5 minutes.
In any event, I conclude from these tests that I am not
overloaded in my current setup. That was the earlier
question.
