Apply zinc oxide arrester (varistor), Cermet II, three-electrode discharge tube, vacuum to avoid overvoltage protection components such as detonator DC parametric measurements. Also can be used for voltage, constant-current power supply, used in other areas.
1. working principle:
When measuring the pressure sensitive resistor, DC/DC converter under certain high frequency pulse drive, 12V DC voltage into DC high voltage test the varistor needs. When in the test tube, control circuit in slope-controlled DC/DC converter, the output voltage to 100V/s up in the 20~1700V rate rises to discharge the discharge tube.
2. application:
Apply zinc oxide arrester (varistor), Cermet II, three-electrode discharge tube, vacuum to avoid overvoltage protection components such as detonator DC parametric measurements.
3. product name:
