Hello, i have in the power supply of a circuit one damaged varistor without marking because of burn.
The input supply is 230V and the damaged varistor is in series with a diode bridge.
I would like help for questions:
1. What is the use of varistor is series?
2. How i can to select the new varistor? What of operation voltage?
