7640/7641 Hipot Tester is a 3-in-1 safety tester integrating AC Withstand Voltage, DC Withstand Voltage, and Insulation Resistance (IR) measurement functions. It provides AC hipot output up to 5kV with leakage current up to 30mA, and DC hipot output up to 6kV with leakage current up to 10mA. The insulation resistance test supports output voltage up to 6kV, with a measurement range from 200kΩ~100GΩ. For production line applications, the system supports multi-channel configurations: the 7641 offers up to 8 test channels per unit and can be expanded via 7508A / 7516A scanning boxes to a maximum of 72 channels. In addition, the instrument supports PC connectivity software and USB storage for test data.
