So, I have this old open-chassis power supply that supplies +/- 12v. It is stamped with the number pr2329, and was manufactured in 1987. Its outputs are a bit odd, though. They're divided into 3 sections. The + section has "+s and +out". The - section has "-s and -out". The com section has +s, -s, and com.
The way it was wired when I got it has the out and s connections connected together, and the +s, -s, and com all connected together, and it seems to work well this way.
What is the purpose of these S connections? Why are they connected together? When would one want them separate?
