[QUOTE="Vipersan, post: 912517, member: 325666"] Yep ..you are quite right .. 12v is not needed really .. 5v is the required voltage for the electronics .. Ideally you could step down to 12 first ...but the 7805 should be ok with a full 24v on the input which is what I'm doing .. I remove the regulators from the pcb and mount on a seperate heatsink ..cos they will run a little hotter than freestanding as they currently are .. but I have already tested with 24v directly on the freestanding 5v regulator for several hours ..and although it runs hotter than I'd like ...it didn't fail and didn't have me worried. rgds VS [/QUOTE]
