I have a 12v/830ma wall wart PS that produces A/C. I need to change it to D/C to power some relays and LED's (nothing too critical, although there are some audio signals going through the relay contacts). The circuit will actually draw about 300ma.
I don't know all that much about rectificaiton or electronics... but I'm thinking that one of those 4 way diode rectifers (full wave?) would do it and preserve the power level (I need to get at least 9 volts out of it to run the relays).
Questions:
1. Is this the best approach, or is there a simpler component(s) that would do the job.
2. Will I get 12volts out of this approach?
3. What diodes (specifically) would I use? I know nothing about spec'ing them... I only just understand what they do![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
