So, let's say you have two boards with a psu on each. In this case, the mnats 1176 rev D's.
The power transformer in this case has a center tap that connects to the boards' circuit ground. With two boards, would I connect this center tap first to chassis where AC ground connects, and then run home run grounds from each individual board's circuit ground to this point? Or should I connect the power transformer secondary's center tap to one board, daisy chain it to the other and then to chassis ground?
And, is it fine to connect the AC power secondaries to the two boards (in series) making sure to keep the same phase?
