Hi to all ,
checking an ac to dc psu of a friend ,
for caps replacement etc..
and there is a connection that I find for the first time ,
please check attached image,
the psu have 2 +18v sections
and 1 +48v for phantom
the "strange thing" is that the +18v out of the bottom section
is connected together with the :
negative / 0V / gnd , of the other +18v section in the middle ,
and the negative / 0V / gnd , of the 48v,
there is a specific reason about this connection or it is an error ?
any help-info about is welcome,
thanks.
