CS9923ECG Photovoltaic integrated auto safety tester

With the development of the photovoltaic industry, the original safety pressure 6kV, insulation 1kV specifications have been applied to the industry's requirements, as well as the grounding resistance test to the DC ground test development. In response to this change, we have developed a two-in-one / triple combination machine with multi-voltage combination and a multi-combination tester, which can meet the safety test of the PV module. Requirements, high efficiency, stable performance, 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 60Adc, test resistance up to 150mΩ, 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 test the body and the circuit in the finished, 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) to measure the automatic stabilization control system
