Hi all! im currently designing a high current, fixed voltage power supply mainly to run a HAM radio, but also for other applications that need a 13.8v high current supply, but i need a bit of advice for part of the circuit, i need a simple but effective way to shut down the power supply if a fault causes it to produce more than around 15v.
still early planning stages of the build but basic specs are these:
230VAC input (UK single phase)
13.8VDC, 30A (maybe 25A) output
linear power supply whih is based around an old microwave oven transformer
everything else can vary
thanks in advance!
