Re: Anyone recognize this power supply?
It could be a forklift battery charger would be a good guess
But very old model is my guess I would test each module by it self just make sure pay attention to how it is hook each other I would expect that to start the charging cycle you probably have at least a minimum of 8 to 10 for it to start charging would be my guess

Re: Anyone recognize this power supply?
not a forklift, the cells are in series - 48v or higher.
it could be an early solid-state charger for garages though. |

It might be from a audio display system used in stores.

My guess, a commercial PSU, ran something in some sort of an transmitter site. Second thought: An shore charger for the battery bank on a boat? Last edited by CapLeaker; 05-14-2020 at 04:46 PM.. |

I think I saw a 1989 date code on that silver-colored 85C 1000uF made by El Cap.
