What it won't do is tell you all the gory details like the max/min voltages seen in the last 5 minutes, what the line frequency is (e.g. 60Hz) etc. - but you will need to check this by findind some documentation / contacts for bkupsd... > [snip] > And what about the lower-end Back-UPS? > Is there a big difference on the way they work (after > all they do come with the serial cable...) I was > looking at the Back-UPS 500 as a solution. I think most the BackUPS are the same - except as they get bigger they last longer, and you may find some have use-replaceable batteries, or facilities for adding more batteries to the system to get longer life etc...
