Hi http://www.deckmonitoring.com/index.html
My understanding is that this is not low cost, but something to ponder for larger systems. ________________________________ From: Darryl Thayer <[email protected]> To: RE-wrenches <[email protected]> Sent: Tue, April 13, 2010 3:03:05 PM Subject: Re: [RE-wrenches] low cost DAS systems Hi Peter APRS world has a revinue grade DAS James could advise you as to multiple power inputs. I also think he as alarm settings.. On a demand reduction system I am just performing monitoring using a very cheap TED. I am working on a building with 800 amp single phase service, I just purchased a couple of CTs busbar clamp size and replaced the factory supplied ones. But I am taking a different route for my inverter generator control.
