Here's a specific example of what I'm thinking of doing with such a scenario:

I'd like to be able to run 465 boards on the bench to test them before reassembling on the chassis. I have a variety of power supplies available to me: TM503 with a PS503A (+/- 20v), a Systron-Donner TL8-3 bench supply that can drive 32v, and more. Can I chain these together to make, for example, +55v without doing harm? Dave On Saturday, May 1, 2021, 02:52:35 PM PDT, Harvey White <madyn@...> wrote:
Definitely.? Most power supplies take a very dim (as in permanently off) view of reverse voltage applied to their terminals.? Most also don't like to be tied to another power supply in parallel unless designed for it. If you're going to charge a battery with a Chinese (or many other types) power supply, put a series diode in so that the supply can't be fed by the battery.
