Hello,
Today I have a dilemma.
I'm repairing an APC XS1500 Battery Backup.
The problem is that a capacitor leaked electrolyte and did some board damage but worst of all, it shorted an EE19 Class 130B transformer which has been rendered garbage because it shorted and burned inside.
The Transformer I need is an EE19 Class 130(B), 430-0601-Z, BCK-EE19-4699A. Maybe you can shed light on obtaining one of these?
This is the exact specs of the bobbin. I contacted CoilTech and they replied immediately. The minimum purchase is 5000 units.
And that is assuming I could successfully rewind the bobbin to OEM specs. Ideally I could get 10 of them to experiment with rewinding.
I'm wondering if you've run into a situation like this with a transformer? what did you do?
How UNlikely is it to ever find a perfect match for an SMPS push pull or even flyback transformer that has burned out on a given board?
I mean, all it takes is a small change in wire diameter, number of turns etc to have a totally different transformer, even with the exact same bobbin, right?
I looked through Mouser and DigiKey but neither had anything close to a substitute / replacement.
What to do?
Thanks
