These are Isopuck model IP200/60. I have 8 of these to sell, needed a couple for projects but had to buy a lot of 10. Details here: https://www.bridgeportmagnetics.com/product/iso-puck/

These do pass the ground through to the output, so no problem with radios which have a 2 wire cord but for 3 wire you'll want to use an adapter or something to ensure the radio isn't grounded when working on it. Not trying to make anything on these, just get them to other people who can use them, so $25 each shipped priority mail.

Apologies for a still relatively "newbie" question, but I do need an isolation transformer.

When using a two-prong adapter, does this newer design transformer operate like a vintage Isotap in terms of isolation? Why would it have a ground reference for medical equipment?

If this is an easy answer and it can replace a vintage Isotap on a bench, I would take one.

Thank you,

Michael

Correct, with a two prong adapter the device under test is no longer tied to ground, just like vintage 2 wire iso transformers which don't even have a ground at all. These medical type iso tranformers were made for isolating from line noise but still keeping ground, so that is why it is there.

Is this what you used in your fantastic dim bulb tester? If so I will take one.
