The Guardian 500VA, 10kV AC, 12kV DC and 20kV DC are four different Hipot Testers designed for specific electrical safety test applications. The Guardian 500VA is intended for high leakage current measurements to 100mA, the Gaurdian 10kVAC for high voltage AC testing and the Guardian 12kVDC and 20kVDC for high voltage DC testing. The Guardian 500VA, 12kVDC and 20kVDC instruments also measure insulation resistance (IR). Selecting the right instrument for the specific application, provides a cost effective solution to special electrical safety compliance testing.

The Guardian 500VA Hipot Tester is an economoically priced AC/DC Hipot Tester for testing products which have high leakage current. With a programmable voltage range from 50 to 5000V AC and maximum current output of 100mA, the unit is ideal for load testing of capacitive devices. The instrument's DC dielectric testing capability covers the range from 50 to 6000V DC, with a maximum current output to 20mA for quick charging of capacitive devices. DC leakage current can be monitored down to 0.1μA.

The Guardian 500VA also performs Insulation Resistance (IR) measurements, similar to DC hipot, except the product's insulation resistance value is displayed directly in ohms. The resistance can be measured over the range of 100kΩ to 50GΩ at test voltages from 50 to 1000VDC.

In all cases, both high and low limits are operator programmable for quick and easy pass/fail testing. These dual limits are essential to ensure that the device under test is actually making contact with the tester. For consistent testing, up to 99 setups can be stored in instrument memory for later recall. An optional high voltage scanner is also available for testing multi-connection devices.

The Guardian 10kV AC Hipot Tester performs AC Hipot Testing only, over the voltage range from 100 to 10,000V AC. With maximum current output of 20mA, the instrument is capable of testing capacitive devices at high AC voltages. The 10kV unit contains many of the features of the 500VA Tester including programmable min/max limits, setup storage and arc detection.

The Guardian 12kV DC Hipot Tester performs DC Hipot Tetsing over the voltage range from 100 to 12,000V DC with a maximum leakage current output of 10mA. Additionally, the 12kV tester provides Insulation Resistance measurement capability over a range of 100kΩ to 50GΩ at test voltages from 100 to 1000V DC. The new improved discharge function allows for fast controlled discharge of the DUT.

The Guardian 20kV DC Hipot Tester performs DC Hipot Testing over the voltage range from 100 to 20,000V DC with a maximum leakage current output of 5mA. Additionally, the 20kV tester provides Insulation Resistance measurement capability over a range of 100kΩ to 50GΩ at test voltages from 100 to 1000V DC. The new improved discharge function allows for fast controlled discharge of the DUT.
