Nope.. These are delivered systems, and I'd have to add another box to the chain, many reasons. It's a little frustrating coming here for help, in that many people try to second-guess the requirements and suggest solutions that might well be viable in some applications, but not mine. I've explored the solution space, and I know what will and won't fly. So, I'm looking for a simple universal input SMPS with 24V output at 2.75A to 3.5A, that will sense an overload, and shut down till the plug is pulled. I know that I'll need to work out connectors etc, but the point of this exercise is to find someone who makes supplies that behave like this, instead of the typical "Burp, Hiccup, or Auto-Restart" modes. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
