or wall-wart/plugpack, you connect one of the AC wires to the center tap,
and the other to one of the two AC inputs. The other AC input is not used.
This means you will be running the power supply as half-wave rectification
instead of full-wave rectification. For the limited load you are proposing,
this won't matter. If you were planning to really load up the supply with
extra modules, you would need to go to two plug-pacs, or a center tapped
transformer like Laurie says in his reply.
