QuadTech Guardian 6000

Introduction

The Guardian 6000 is four instruments in one providing AC Hipot, DC Hipot, Insulation Resistance and Ground Bond measurements from a single test connector in one versatile instrument. This provides a cost effective solution to electrical safety compliance testing with maximum flexibility for present and future requirements. Performing multiple electrical safety tests in one unit can reduce test time, increase productivity and reduce the number of instruments requiring calibration.

Description

The Guardian 6000 AC Hipot Tester performs AC dielectric testing (hipot)over the voltage range from 50V to 5000VAC RMS. The maximum leakage current of 40mA RMS makes the Guardian 6000 ideal for testing devices with high leakage currents such as power supplies which have large filter or “Y” capacitors for noise reduction.

The Guardian 6000 DC Hipot Tester voltage range for DC dielectric testing is 50V to 6000VDC with a resolution of 1V. 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. Leakage currents can be monitored down to 0.1µA.

The Guardian 6000 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 100kΩ to 50GΩ with test voltages from 50VDC to 1000VDC in 1V steps.

The Guardian 6000 Ground Bond provides up to 30AAC for ground bond testing. The test current can be programmed from 1A to 30A in 0.1A steps. Hi current limit, test time, frequency and open circuit no load voltage can all be programmed. The offset feature can automatically compensate for any lead resistance.
