The Guardian 500VA, Guardian 10KV AC, and Guardian 12KV DC are three different Hipot testers designed for specific electrical safety test applications. The Guardian 500VA is intended for high leakage current measurements to 100mA, the 10KV AC for high voltage AC Hipot testing and the 12KV DC for high voltage DC Hipot testing. Additionally the Guardian 500VA and 12KV DC testers include insulation resistance measurement capability. Selecting the right instrument, for the specific application, provides a cost effective solution for electrical safety compliance or production testing.

The Guardian 500VA is an economically 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 in applications where a product safety standard requires or recommends a 500VA Hipot tester. 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 0.1ľA.

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. This resistance can be measured over a range of 100kohms to 50Gohms, at test voltages from 50 to 1000V DC.

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 50 setups can be stored in instrument memory for later recall. An optional high voltage scanner is also available for testing multi-connection devices.

Guardian 10KV AC Hipot Tester The Guardian 10KV AC performs AC Hipot testing only, over a voltage range of 100 to 10,000V AC. With a 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.

Guardian 12KV DC Hipot Tester The Guardian 12KV DC performs DC Hipot testing over a voltage range of 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 100kohms to 50Gohms, at test voltages from 50 to 1000V DC.
