What is it?

[al2n]

Went to a storage auction yesterday and came home with a van full of stuff. In one of the boxes there were 5 of these things, all but the one pictured is still in the original box.

Would a transducer like this have a use in ham radio? Ebay prices are all over the place with transducers so I am unsure as to value. Any information is welcome.

The transducer is a device that should allow you to accurately measure the AC current. It appears that this is 0-5A on the input, and so the DC output will be an RMS representation of that AC.

The 1mA into 10k looks scary though.

Looks like a real steal.
