Just asking a... generic question: I planned to have (as I already did in my previous home) 12 or 24Vcc around the house to be used for remote device, small actuators and such. I'll also have 12V (traditional supply - no switching) for audio, using 2x0.50 + 4x0.22 shielded cable. But, the other one, will go around via CAT5e cable, using a similar-to-PoE standard, powered via a 2.5A switching supply. I'm just wondering if it's better 12 or 24V... The remote devices are PIC16F628 or 18F1320 based... @5V. A linear regulator with a small dissipator is ok (tested for years @24V). I just believe that I may never need 24V - it would be most needed in industrial field, not at home... But, still, I'm left undecided... -- Ciao, Dario -- ADPM Synthesis sas -- http://www.adpm.tk -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
