Re: [CAD_CAM_EDM_DRO] Center tapped transformer

Look at the center tap wire. If it is a loop or 2 wire ends then you can
split them apart to get 2 30 volt windings which can be paralleled to
double the secondary current. To make sure that you get the phasing of the
2 windings right connect a light bulb in series with the primary to limit
the current. Parallel the secondary windings and apply power with no load.
If the bulb lights the seconday windings are out of phase, reverse them and
try again. You should get the proper voltage on the secondary with the bulb
unlit.
