Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <DNAForInfinity-at-aol-dot-com> Hello, I just recieved a DC power supply from a friend who didnt know what it was, it turns 120 V input into a 13.5 V DC 2.5 Amp output. I really dont know what this would be used for, can anyone help me out here? Thanks Alot, Dan Finfer
