You know, I actually didn't pay too much attention to the surge rating. The IT guys use this at work to protect servers and workstations. We have all sorts of power bumps and brownouts as local power gives out and the building's APU kicks in. No complaints from the IT guys and they say the units work great. We're protecting a lot of very expensive stuff with them too. The connected equipment warranty is $200K including direct lightning strikes. Maybe the Joule rating varies between manufacturers...kind of like power ratings of amps and AVR's. Maybe the fact it's a battery backup and provides voltage regulation has something to do with it. If anybody else has any insight, I'm sure it would be appreciated by all.
This thread is interesting reading. The last post in it makes a lot of sense. http://www.digitalhome.ca/forum/show...t=Joule+Rating
