Hey all,
Have been on the lookout for a schematic kinda like a crowbar circuit but instead of using an SCR and blowing a fuse I want it to pull a relay and disconnect the load.
My fancy lab PSU has this feature and I want to use the circuit in a high current PSU .
Have looked all over the net.
Have had an idea with a shunt resistor and even an opamp but not really sure which way to go.
Anyone got any good tips, ideas or a circuit.
Cheers
