Thank you Arby...just what I was looking for!
Ok, so now I'm lost, do I put this back into my power supply or is this my power supply? How do I get -5v and -12v? or do I need it?
This replaces the ac portion of your old supply. You wire the transformer back to the original power supply, and it takes care of the regulation and such.
ok, that makes sense, but when I measure the voltage on my existing transformer its like 140v, 120v, on the secondary (while its still in the power supply). I'm sorry but I'm having a little trouble. Heres how I think it works and you tell me, it comes into the transformer as 120vac and then it is supposed to be 3.3vac, 5vac, 12vac out, then into some rectifiers. But when I use my multimeter I get strange readings.
Yeah, I got lost too trying to work out where everything connects. BTW. your transformer may have the primary winding split into 2. one on the very outside, and one on the very inside, and it may also have 2 copper strips..
ok, I think I am starting to understand this thing, we dont care what the output of the transformer is, just as long as it is the same as what it was before we started. We are just tring to get the same output from the transformer off 12vdc and we were with 120vac. Now, what about the other trnasformers that are running off the ac section, do we not need them?(I have 2 small ones) are we bypassing the ac section all together? so I just put the secondary part of the transformer back into the old location and use the new circuit we just made for the input on the transformer. I hope I got this right.
ok, what happends if you break the ecores? Are they no good now? Or can I piece the two parts back together?
I dunno, have to ask presslab
I broke one, but I have so many old at power supplies sitting around that I just grabbed another one
