AC Hipot Tester performs AC dielectric testing (hipot) over the voltage range from 100V to 5000VAC RMS. The maximum leakage current of 40mA RMS makes the Guardian 5000 ideal for testing devices with high leakage currents such as power supplies which have large filter or “Y” capacitors for noise reduction. Both the actual test voltage and total current are displayed during testing.
TDC Hipot Tester voltage range for DC dielectric testing is 100V to 6000VDC with a resolution of 10V. The maximum current leakage is 20mA which allows quick charging of capacitive devices. A quick discharge of the device when the measurement is complete, also minimizes test times.
Insulation Resistance measurements are similar to a DC hipot but rather than displaying leakage current, resistance is calculated and displayed. The insulation resistance can be measured over the range of 10MW to 10GW with test voltages from 50VDC to 1000VDC in 1V steps.
