what is it?

I am looking for some help on an item I won in an auction. here are my assumptions about this item.
1 master 24 volt input with master switch on front.
8 individually switched outputs.
supposedly it is a power filter for an mrap.
i have not opened it up yet, but the thing weighs a ton.
what else is there to it? power in, switched power out is there something i am missing or another use for this item i am not considering?

I don't know the actual end use of this thing, but in general, it's a nice box for anyone with a bunch of pieces of 24V equipment in their truck. They're not just on-off switches, but circuit breakers rated for the amount of current printed on the front label of each switch. That's a nice, compact, and durable way to assemble such an arrangement.

Part number? NSN?

Thats cool! Do you have any spares? I'd be interested in one.

[h=1]UEC 0589A02-001_A Direct Current Filters[/h][h=1]NSN 5915-01-622-3588[/h]would it work if i used 12 volt instead of 24?

Well...here's the manufacturer's page: http://www.uec-electronics.com/mrap-c4isr-vehicle-power-distribution-unit-pdu-2/
Also...look at the freakin' prices we're charged for them:
As much as $14,700 if you only order a few, or as "little" as $2,261 if you order 250 at once.

i feel a need to open one up, at those prices, they should be gold lined

So I opened her up
