Power supply info needed

Post by JAYMZ »

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.

May the Schwarz be with you.

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..
