CTIIXX PV safety tester has 3 models CTII21/II23/II33 to choose, as a all-in-one instrument, each model combines AC/DC withstanding test, leakage current test and insulation resistance (IR) tests, hence they are also called hipot tester, DC/AC withstand tester and insulation resistance (IR) tester.

CTII21/II23/II33 Hipot Tester has programmable output voltage 0.5kV~ 5kV AC and 6kV DC, insulation resistance test range 100kΩ ~ 99GΩ.
CTIIxx is featured in both Arc detection and power detection functions.
With optional RS485 interface and MODBUS protocol,CTII series Hipot Tester can easily integrate with other supporting facilities to achieve automated testing

CTII Hipot Insulation Tester is most applicable to AC Hipot, DC Hipot and insulation resistance for the following application:

• Automated test system
• Household appliances
• Transformers, motors
• Electrical equipment
• Heating appliances
• Photovoltaic industry
• New energy vehicles
• Electronic components
• Medical equipment

CTII91A comprehensive tester is a three-in-one instrument combining with withstand voltage, insulation and ground continuity for photovoltaic industry automation test equipment.

CTII91A comprehensive tester complies with photovoltaic standards IEC61215, IEC61730, suitable used in solar PV module for hipot testing, insulation testing(IR), grounding testing, wet leakage testing, etc.

CTII91A max withstand voltage is 8kV DC and 10kV AC and current range of 10A~60A at 0.01A resolution for ground resistance test.
