Power supply info needed

I have received a couple of these power supplies from a friend of mine and I need to get some info on them. Manuals, wiring diagrams, sound advice, or shipping address(So my wife doesn't yell too much :P)...

Here's what I have....

The frame has a part number of TPN1185B, the circuit board (which has a switch for float or equalize) has a part number on it of TRN7241B

And this is what it looks like on my wife's footstool...

I have a few educated guesses on it... but I would rather have someone back me up on it so I don't burn my house down trying to figure it out.

MSF or PURC

I have a TPN1186A here that looks the same, but no provision for battery backup/charger. It's from a PURC 5000.

Is this what you're thinking it's from?

Jaymz,
I agree with Josh, its from the MSF series. Unfortunately I don't have any of my manuels here to give you the specs on it.(I lent them out) If your still searching when they return I'll dig further.

Ok. I think they came out of some remote bases or repeaters that were donated or whatever. I'm not completely sure as to models and such..

I basically would like to know where everything gets hooked up and what the power ratings on the unit are. And I'm in no terrible rush. I got these and a 19 inch rack cabinet about a month or 2 ago.

If nobody does this before I get home tomorrow (nursing clinicals) I will look in my MSF 5000 book and see if the numbers match.

aww hell gimme a minute


according to my MSF book it is a 500 watt out 60 Hz 110 volt in w battery revert.

it'll give you anywhere from 13.1 to 16.1 (IIRC) and about 35 amps. I have one for my test bench and it's a pretty awesome rig. it'll run a old jetsonic with everything going for more than a little while. 8)

I mite add here, it IS a MSF5000 batter revert power supply that uses a feroresonate winding in the transformer with a capacitor to somewhat regulate the 14 volts. WATCH OUT the "flyback" or feroresonate winding and capacitor has 300 AC volts on it.
There is also a added circuit to help contol the capacitor on the "flyback" winding, controling the battery float voltage to about 13.8 volts..
