Default Power supply question


"klem kedidelhopper"

Now here is the dilemma. I haven't tried to put all this together yet,
but I know that once I rectify and filter the 24VAC I'll probably end
up with something like 30VDC out.


** Likely about 35VDC unloaded


I could add some series resistance either before or after the bridge,
but the voltage drop across this resistance would vary depending on
the total load and I'm not sure how well such a scheme would work.



** A string of say 20 x 3A diodes is the cheapest solution.

Wired in series with the "+" terminal of the bridge, all mounted on a tag
strip.

Drops the DC level by about 12 to 15 volts, depending on the load.
