NOTE This is a Short form kit (PCB and instructions only) for a dual crowbar intended for use with +/- power supplies as used in mixers etc, audio equipment etc.
A Crowbar is a circuit that places a short circuit across a power supply in the event that a fault occurs that results in the power supply providing a higher voltage than the circuit can handle. The crowbar tripping will usually result in the power supply going into current limit mode or (in the event it is completely cactus) blowing supply fuses. This board supports two independent crowbars, one set up for a positive supply rail, the other for a negative supply rail, this makes it ideal for protecting audio equipment such as mixing consoles.
