I've been charging (reforming)capacitors since Saturday and I just have
a couple of questions. First off I an using a 120V variac and a bridge
rectifier this is fed through my multimeter set for 0-300MA. I am
slowly increasing voltage keeping the current limited to between 40-
100MA. I have managed to bring the voltage up to full line voltage over
a period of about 25-30 hours. This translates to about 170VDC. I can't
get the caps to fall below about 50MA of current draw at 170VDC. The
caps are about the size of a soda can and are 200VDC @ 5400uf. Is this
a good current draw for this type of cap? Would it be advisable to find
a P/S that would deliver the full 200VDC rating for the cap to reform
at their maximum voltage? Note: The caps (6ea.)will be operated at
about 120-125VDC when they finally get installed in the PS that I am
building. I am also building a 10A soft start for them.
Thanks,
Larry Olson
