FC-2G discharge tube varistor tester

Under the drive of high-frequency pulses set by the FC-2G discharge tube varistor tester, a 12V DC voltage is increased 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 at a rate of 100V per second within the range of 20-1700V until the discharge tube is discharged.

The FC-2G discharge tube varistor tester is suitable for zinc oxide lightning arresters (varistors), metal ceramic secondary and tertiary electrodes. Measurement of DC parameters for overvoltage protection components such as discharge tubes and vacuum protectors. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.
1. Working principle:
When measuring varistors, DC/DC converters are used. Driven by a fixed high-frequency pulse, the 12v DC voltage is increased 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 at a rate of 100V per second within the range of 20-1700V until the discharge tube is discharged.
2. Scope of use:
Suitable for zinc oxide lightning arrester (varistor), metal ceramic secondary and tertiary electricity. Measurement of discharge tube parameters.
3. Product nickname:
Varistor tester, discharge tube tester

FC-2G discharge tube varistor tester is suitable for zinc oxide lightning arrester (varistor), metal ceramic secondary and tertiary electricity. Measurement of DC parameters of discharge tubes. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.
It has functions such as high voltage short-circuit protection, overcurrent protection, high voltage preset, range adjustment, etc., and the high voltage self discharge time is less than 0.5 seconds.
● It has a self checking function.
The measurement data is displayed by a three and a half digit LCD digital display, with high accuracy.
During measurement, the range can be pre-set and an audible prompt can be emitted for zero range testing during the measurement process, which is suitable for device grouping and inspection discrimination.
Choosing continuous measurement allows for uninterrupted testing of batch samples.
The panel has simple functions and is easy to operate.
Lightweight and easy to carry.
