Hi Guys
i am looking for a more sophistocated way of preventing someone supplying a capacitor outside its given voltage.
eg 25V capacitor
my method was to use a zener and a relay in series to prevent anyone supplying a voltage greater than 25V
using a zener say 10V and then using a relay where the contacts pull in around 15V. Once a voltage over 25V is applied the relay opens and no more voltage can be applied to the capacitor.
I was thinking this would be possible with an op-amp somehow sensing the voltage across the capacitor. any ideas?
