Thanks, Dick. The last post I had on personal files was back in May. OK.
Here goes:
I've been given an inoperative regulated power supply (120 vac to 13.8
dc) with a generic circuit schematic that doesn't seem to represent what
is actually in the supply. The only identification marks on the unit are
(a) the capital letters "ER" (stylized, the E consisting the three
horizontal bars only, followed by the R, and both letters
leaning/slanted to the right), and (b) the apparent model number PS-109.
It states that it is rated at 13.8 volts (fixed), amperage at 30-32.
Googling various combinations gets nothing useful.
Does any one have any idea who made this thing? Any leads will be
appreciated.
73,
Max, K5OVW
