Summary

Photovoltaic safety tester is used to test PV module, cable, connector, terminal box, …etc which can deal with high voltage and high sensitivity insulation test. There are two functions that are high voltage test and insulation resistance test in total.
According to the IEC61730 standard(photovoltaic module safety qualification—part I: Requirements for construction which describes the fundamental construction requirements for photovoltaic modules in order to provide safe electrical and mechanical operation during their expected lifetime), the definition of PV module application is divided into A, B, C.
The current measuring terminal can choose the grounding mode or the floating mode. Insulation voltage withstand test of photovoltaic module is based on the application of IEC61215/61646 and the maximum voltage of the system.
Maximum test voltage for the application class A:2000V plus 4 times the maximum system voltage
For the maximum voltage application category B:1000V system 2 times
According to the calculation of a maximum voltage of 8000V, CS9923GS, CS9923G is based on this standard production
According to the calculation of the maximum voltage B 6000V, CS9922G, CS9922GS is based on this standard production

uDo the insulation/hipot/grounding resistance test on PV module battery, controller and battery inverter.
uWithstanding voltage/IR/GR three functions are integrated in one tester.
uOnce users finish setting parameters, the tester will do all the above tests. With fast test speed, stable performance, saving time and work, high efficiency, our tester is special widely used in auto product line.
uPrecise test between metal parts and earth terminal of all the solar system
uConstant current output and without effect of load and mains supply, which guarantees that the test data is accurate and stable.
uAdopt DDS theory, this tester can generator standard sine waveform to drive the Linearity amplifier output, which control the wave crest range within 1.3 to 1.5.
uIn the testing of grounding resistance, four-terminal method is accepted, high precision.
uHipot and IR test on solar panel, controller, storage battery inverter.
uWith the function of electricity safety wall, It can detect whether the input power is correct.
uAfter finishing DCW and IR, it can discharge electricity within 0.2s automatically which can protect the safety of users. Whether it is turned on/off, no voltage overshoot and no damaged to the DUT.
uIt adopt DDS theory generating standard sine waveform, Linear Power Amplifier drive high voltage output, the pure waveform, loss distortion, (less than 1%) made our tester in leading edge of this industry.
uRS232, RS485 interfaces are optional, PLC interface is standard.
