Please pardon my ignorance. I know little, I think less and less every day,=
 about power supplies. I have always just found one that works and gone wit=
h it. However, I had always presumed that they would behave, more or less, =
like batteries. Put them in series to increase the voltage, parallel to inc=
rease the current. What am I missing here? Series to deliver more current?

Thanks,
Allen

I doubt that these supplies are meant to be run in series the way he=20
connected them.
