What kind of transformer is this?

mdkmdk · Jun 24, 2022

Hello everyone,
I would like to know what kind of transformer is this so that I can buy a new one, I am attaching some photos. There is no writing on the transformer. It is located in a furnace for goldsmith use, in which there is a Crydom D2425 relay and a Fagor B40 C5000 / 3300 rectifier bridge, the current of the house is 230V 50 hz. In the photo I drew a red arrow to indicate a thread that otherwise would not have been easily seen. If you could kindly tell me the related specifications to look for online to buy a similar one I would be grateful, thanks in advance for the answers.

need to see more. e.g is the transformer wired to the relay, which appeatrs to require a 3V -32V input, so a 12V or 24v V feed would be logical.

Is this related to the other thread? If so then your approach of gradually changing every part until you fix it is possibly not a good one.

“What kind of transformer is this?”

Sigh…. Ok. Someone had to do it…..

Generally, if it’s a wheeled vehicle or a dinosaur, then it’s an Autobot.

Aircraft, insect or cassette tape player. It’s a Decepticon.

What is wrong with the transformer? Modern transformers like this are very rugged and rarely fail on their own. There are millions of different transformers, many are designed and built specifically for a product or application. I often work with very old equipment and any failed transformers get sent away to be rewound as finding an off the shelf replacement isn't going to happen.
