CS9950ED DC grounding resistance tester

CS9950EDDC grounding resistance tester

With the development of photovoltaic industry, the original safety pressure 6kV, insulation 1kV specifications have not applicable to the industry's requirements, as well as the grounding resistance test to the DC ground test development. We have developed a special anti-voltage insulation up to 10kV, and the integration of DC grounding function of the combo / triple combination machine can be completed once the PV module safety testing requirements, high efficiency, stable quality of the product In the test of small current resolution of 0.001μA, insulation resistance of 100GΩ DC grounding resistance of 100A, so as to ensure product quality

DC grounding resistance of the maximum output current of 100Adc, test resistance up to 510mΩ, the accuracy of up to ± 1%

Compliance with UL1703- flat panel solar module safety certification standards and IEC61730-1 photovoltaic DC grounding resistance test requirements

Can automatically complete the PV module voltage, insulation, DC grounding resistance test

With the rapid discharge function, the tester can be in the DC test finished 0.2s time to be tested body and the circuit in the discharge, to ensure the safety of the operator

Pressure, insulation constant voltage output, DC grounding resistance constant current output, to avoid the input voltage instability and load changes to the output changes

Fast voltage rise time (within 100ms) measurement automatically determines the control system
