The CS9922G CS9922G-1, AC/DC Withstanding Voltage/Insulation Resistance Tester, is the test instrument that can handle the insuration test with high voltage and high resolution required for the evaluation of the PV module, Cable, Connector, and Junction Box. The CS9922G/9922G-1 are equipped with functions of the AC/DC withstanding voltage testing and the insulation resistance testing accompanied with the features and performance of IEC61730, and both of the two extends additional features and specifications exclusively applied to the PV module testing. Furthermore, the CS9922G, CS9922G-1 improve the current measurement accuracy of the DC withstanding voltage testing from the original 0.100mA to the current 0.010uA.
- Up to 5 kV/20 mA(AC) and 6kV/10mA(DC) withstanding voltage test
- Perform insulation resistance testing in the range of -50 V to -1000 V / 1 M to 50.00 G
- Applies for the testing of IEC61730 standard
- High-precision current measurement, 1 μA of the setting resolution for judgement
- Rise-time control function makes a voltage to be increased slowly and it will not give effect of the stress to the PV module
- The judgement method of the insulation resistance test can be selected by using the current value in addition to the resistance value
- The phenomena of voltage appearance by the dielectric absorption, the test time can be up 999.9 seconds
