This crowbar protection circuit for non-regulators blows the fuse when the load voltage exceeds a certain value. The configuration with component values can be seen in the previous circuit.
The circuit shown is from an old European publication. In it we have the way to activate a relay...
We found this circuit in a European publication from the 1990s. Transistors are still common types...
