Funky Transformer

Post by Super Mulletman »

I took apart my now old alarm clock and pulled out a tranformer with the positive and common from the outlet being turned into 3 wires = 2 red, 1 white. I tried to tell the voltage and what was common with a voltameter, but every connection between the 3 wires gave either 6 or 12 positive volts. I want to run the clock off batteries and I know that it shouldn't take mcuh amperage at all, but I just can't figure out the wires. It's fairly small transformer with the code on it's side being:

E153470
El-28 HF002

Help!

Sorry, but I'm currently camera-less. I know it's a transformer because there's only one large object between the clock and the outlet, and I get the feeling that a rectifier won't cut it. It's just a transformer with 2 wires on the primary, and 3 on the secondary.

It doesnt make sense. A freaking DC uses a rectifier but a clock does not :?

umm...jack, if it was a rectifier the clock would be getting 110V DC....

It is possibly a center-tap transformer. Hold onto that, because it is the most rare and expensive component when making an inverter.
Warranty-Voiding fun!

Well that shouldn't be too hard then. I was deciding if I should just take off the LED panel and use it seperately, and if the transformer is difficult to come by, I may just hold on to it and leave the rest of the clock alone.
