I’m trying to figure out what is -S, +S and PS could stand for?
I checked voltage on PS, it’s 0.05vdc when idling and 0.2vdc when 10Amp load applied on 12V rail.
I didn’t attempt to test S terminals, as I have no clue what it could be and how to safely test it.
What I’m trying to accomplish:
I would like to add a switch on low voltage side and control it with ESP-12E board
My assumptions are S stands for switch, 5V rail is always On and 12V rail can be switched On/Off.
There is no schematic available for this PSU (well, i coudnt find one). It’s made by Skynet Electronics, model PEL-R307. PEL probably stands for Pelco. There was two of these PSUs in rack mountable shelf. I’m assuming for redundancy.
100-240V 50-60Hz 4A
12Vdc 21A
5Vdc 0.1A
