"CARON specializes in problem solving and providing solutions to electromagnetic (EMC), electromagnetic interference (EMI), transient voltage suppression (TVS), electrostatic discharge (ESD) and safety related needs of today's complex electronic systems."
If I had to guess, I'd say its related to that. If it looks like a power supply, plug it in and poke around with a meter to see what it puts out. I doubt its terribly useful for anything other than the original application though.
