Hi everone, nice to be here
Problem overload protection for an Aeroplane for radios and transponder min 10volts max 16v
Crowbar circuit
Scr + 15 volt zener>>>>>> problem as temp goes up the zener`s accuracy goes down ie now 17 volts meaning a fried radio.
So a 5.1 volt 1watt zener with a 1/4w resistor.

Thanks in advance
And an early happy new year to everyone
