Here's the C/L ad if still up, http://southbend.craigslist.org/tls/3166129936.html if not I can post pics. It's military, looks new as it still has plastic on the panel. I assume it's some kind of welding power supply. It weighs about 500#, has 2/0 welding cable on one side, 8/4 on the other about 50; of each,3 phase I assume. 4 60amp breakers all connected, 28VDC, model jla 5592, p/n jla 05-1111, made by Spectro Sort,DC amp gaude goes to 60 amps. Let me know if I wasted my $50. Thanks for any & all help!

28VDC is fairly common in older MIL stuff, at least, dunno about new. Does NOT have to imply anything about welding, and in fact probably does not, since welding is commonly variable voltage, constant current, for stick/tig.

I have an old Eclipse 28VDC 150A generator, for instance, which is probably from a tank. Similar ones were used in B-29 aircraft. That power supply looks newer.

Might be a hell of an anodizing rig.

Well I got some nice cable anyway & as heavy as the beast is maybe a load of copper or I could make a super battery booster for my 24V Tractor. That's a great idea as some dummy like me thought he turned off the radio in the cab but really only tuened it down last fall & drained the batteries. I really think it's new. When I offered $50 I hoped it was adjustable output. Thanks for the help!

Power source for a derusting tank, Go Big or Go Home! I've seen wanting to try electoplating & have brass, co[[er, bronze (I think) zins $ several others from the Thermal Spray wire system.

New info. It has a tag dated 1999 looks like it was made for the US Border Patrol so you Northies trying to sneak into Michigan to grab all our free-near free-or payed to haul away machines Watch Out! I've got you covered! I don't know what with but it looks wicked! LOL!

According to this:

...there is a place called Alamo Aircraft in San Antonio that has 8 of them for sale. Maybe they can tell you something about it.

Thanks, I'll call them Mon AM.

Could be the starting source for an axillary power unit (APU - or gas turbine engine hooked to a generator). I believe most of the APU's I've seen are in the 24V range to get them started.

Any idea of the input voltage? It's 4 wire so I assume 3phase.

Have you opened it up to have a look inside? Often you can find markings on sub-assemblies or components that may give you a clue as to input voltage or other info. Maybe a few photos posted here of the guts will get some of the fertile minds that lurk here going to figure out exactly what you have there. I don't know what it is, but I sort of want one now...
