This circuit was found in a 90s Radio Electronics. MOSFETs must have excellent heat sinks and heat and the board layout carefully planned to withstand high currents.
One of the problems with common multimeters, especially analog ones, is that their low resistance scales...
This circuit was found in old documentation, but the setting applies to any operational. Resistors...
Vz determines the trigger point for this protection circuit. The SCR doesn’t need to be mounted on a...
