Electric Fence Controller Triac

摘要

I've built the Electric Fence Controller from the April 1999 issue. I couldn't get formers for E30 cores so I used E29 assemblies instead. As they're bigger, I had to redesign the PCB and stretch it. I originally tried using a BT137X 600E Triac from Jaycar. However, when I fired it up, it lasted two pulses then died. The second one died even faster. It might be that the gate voltage is too high.
