What is this? Isolation transformer?

I think it is, but the power supply also had an isolation transformer attached to it... the wiring went from the wall, into this, into the isolation transformer on the power supply...

If it matters, this was in an Italian cab which was run in Canada... Step down transformer maybe? I dunno.

EDIT: This is also canadian made, and looks like it was added into the cabinet after production. The ISO on the power supply works fine, I am using it on my test bench right now...

That's a good old Hammond Manufacturing isolation transformer. They seem to be very common around here. A few of my games came with one, and they're just regular 1:1 120V 300VA iso's, not step-down or anything. That label on the front should give you the specs. They also make nice boat anchors!

Yeah, it's hard to make out the label but I think it's 115 in 115 out. So, I can use this on my test bench to power a monitor & a PC power supply, right? I want to put the one I'm using now back into the cab.

EDIT: and yes, it's heavy as hell.

DOUBLE EDIT: Do ATX power supplies need to be attached to the ISO as well or can they be plugged in direct to the wall, in a JAMMA test bench situation? Can I get away with just running the monitor through the ISO?

I'd run only the monitor through the iso... the power supply doesn't need to be.

Any way to test if the ISO is indeed working properly? I mean, of course I can test 120v in and 120v out.. but how can I prove that it's isolating properly, short of plugging in a monitor and seeing if it blows?
 
I suppose you could do a continuity test between primary and secondary windings - there should be no electrical connection between the 'input' side and the 'output' side. I usually plug in a lamp to make sure the output is near 120V under load.
