Re: [CAD_CAM_EDM_DRO] Transformer question

Tom, If you're really careful, and the secondary winding is
on the outside, you could maybe pull a few turns off the
sec. to cut the output. How about putting in SCR's on the
input to limit the output? I suspect the zener will run
pretty hot, dumping that much power.
