Dear forum,
I have been given a battery powered 6v-12v electric fence machine to repair that keeps cows and sheep from escaping the field. It can output up to about 5 or 6Kv that connects to a long wire that keeps them from escaping or running out on the road.
I have done my tests on the circuit board and the output transformer is blown on the primary side winding. The secondary side of the transformer connects directly to the electric fence wire.
I have removed the transformer and checked the primary side voltage on the circuit board which reads about about 6 or 7 volts pulsating on and off so that verifies to me that the control circuit and everything else is ok.
The problem is I don't know what type of transformer this is, obviously this a step up from about 6 or 7v to about 5 or 6Kv or so, is this a flyback boost type or a custom made one, I'm not sure!
Its a small pcb mount one with no markings at all on it, here are a few photos;
Can you tell me what type of transformer this is and where would I get one as I have searched with no results? It doesn't need to be the exact dimensions,
Any alternatives would be greatly appreciated?
