I need a cost effective solution for a 12 volt fixed DC power supply for a project I am working on which requires the use of a three prong plug so I have Access to the ground wire. Maximum current would be less than 1 Amp. I can add my own 5 volt and 9 volt regulator with input filter capacitors to get my required voltages.
Access to the ground wire is most important then a solid construction that would be UL approved and an enclosure that could mount easily to the bottom of a wooden shelf.
Old computer power supplies would seem ideal but they are large, and can they operate properly at low average currents of 100 ma?
Thanks for your input , Christopher .
