FC-2G (B) Lightning Protection Component TesterThe varistor tester is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors) and metal ceramic two - and three electrode discharge tubes. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.

FC-2G (B) Lightning Protection Component TesterWhen measuring varistors, the DC/DC converter drives a certain high-frequency pulse to increase the 12V DC voltage to the required DC high voltage for testing varistors. When testing the discharge tube, the slope control circuit controls the DC/DC converter to increase the output voltage value within 5-1700V at a rate of 100V per second until the discharge tube is discharged.
