I need a circuit to prevent voltages above 24VDC from getting to a component. I am supplying it with 12VDC and simply want to make sure that in the event of a surge or blown fuse, the voltage does not exceed 24VDC.
I did some online searching, and found a circuit on this site that might fit my needs, but it has about 15 components in the circuit. Can this circuit be quite simple? I thought the appropriate Zener in parallel with the load would be sufficient, but it looks like I am wrong.
The 12VDC is coming from an AC-DC power supply, and the load is not supposed to draw any more than ~ 3A.
Thanks in advance for any help provided.
