QuadTech Inc

A complete dielectric testing solution, with three models from which to choose. The Sentry 10 for AC Hipot Testing, the Sentry 20 for AC/DC Hipot Testing, and the Sentry 30 which combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit. The front panel of the Sentry makes it easy to operate. Digital Display and user-friendly control allows test parameters and limits to be set easily without the high voltage activated.

The three units are also available in a CE mark version, the Sentry 15 for AC Hipot, Sentry 25 for AC/DC Hipot, and the Sentry 35 for AC/DC Hipot and IR.

The Sentry Series of electrical safety testers are advanced digital hipots with load and line regulation to ensure measurement integrity. Multistep capability allows the user to perform up to two tests in a sequence such as AC Hipot followed by IR

The Sentry 10/15 AC Hipot Tester performs AC dielectric withstand (Hipot) tests. The test voltage can be programmed in the range from 100VAC to 5KVAC with a resolution of 10V. The maximum total output current is 15mA.

The Sentry 20/25 AC/DC Hipot Tester has all the features of the Sentry 10/15 with the addition of DC Hipot capability. The test voltage can be programmed in the range from 100VDC to 6kVDC with a resolution of 10V. The maximum total current is 7.5mA (5.0mA for the CE Mark version, Sentry 25)

The Sentry 30/35 AC/DC/IR Hipot Tester has all of the features of the Sentry 10/15 and 20/25 plus measurement of insulation resistance. The IR measurement range is from 10M to 10Gohms with test voltages from 50 to 1000VDC.

Quick Discharge: In both the DC Hipot and IR the device under test is discharged back through the HV transformer. This technique results in a rapid safe discharge.

Ground Continuity Check: All of the Sentry units have a ground continuity check feature to determine that the resistance, between the ground blade of the power cord and any exposed metal on the product, is less than 1 ohm.
