This Crowbar project can be used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuit connected to the power supply. It operates by putting a short circuit and fuse blow across the voltage output, like dropping a crowbar across the output terminals of the power supply. The circuit […]
