The CS9933ET series Programmable AC/DC Withstanding Voltage/Insulation Resistance/Ground bond  Tester, is the test instrument that can handle the insulation test with high voltage and high resolution required for the evaluation of the PV module, Cable, Connector, and Junction Box.  It can be finished three test that is AC/DC hipot, insulation and ground resistance automatically. With fast test speed, stable performance, it is widely used  in production line. CS9933ET series Programmable PV auto Safety tester the insulation maximum test voltage can be up to 5000V dc. CS9933ET series PV auto safety testers are included four models, that is, CS9933ET(insulation 1000V), CS9933ET-1(insulation 1500V), CS9933ET-2(insulation 2500V), CS9933ET-3(insulation 5000V). The difference among them is the insulation resistance test voltage. 

• Applies for the testing of IEC61730:2004 standard, IEC61646:1996 and IEC61215:2005
• 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

CS9933ET-3 The main test parameters are as belows:
