Measuring UPS Efficiency – Help!

Saturday, April 17th, 2010

One aspect of determining our Power Use Effectiveness (PUE) is to understand how much energy is "wasted" by our UPSes.  This is especially important as we look to move from many small rack-mounted UPSes to a more central approach.  We've been quite confused in reading about the relationships of Real ...
