not a combination of the 2.

it is powering analog circuitry in the NC rack, LM747 for example.

i always get +/-12 vdc at this point, and i am sure the wier is either 2 12,s or 2 15's
not one of each.


a far as plus and minus goes on the 2 twelve volt supplies, you just wire one output reverse polarity, this is normal, so don't worry.

any competent electrnic tech can figure it out for you.......
along with the sense lines.
I have a Robofil 200 that lost the -12v in the power supply; can I just reverse wire in a separate 12v power supply, or does the circuitry need dual tracking regulation?
