I have an experimental device that produces a voltage rising from 0V to 30V over 5secs and then steady at 40V and this voltage is monitored using a multimeter.
Occasionally there may be overvoltages , like a spike of 600Volts. I want to build a overvoltage protection circuit that will be placed between the multimeter and experimental device for protection. Does anybody have any idea about how to build such a circuit using diodes capacitors etc?? The overvoltages i get from my device can be a spike of 600V or even a constant smooth voltage of 600V. I need to make a voltage limiting circuit to isolate and save my multimeter from damage.
