Economical AC/DC/IR Hipot Testers
Introduction
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.
These 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.
Description
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 Testerperforms AC dielectric withstand (hipot) tests. The
test voltage can be programmed in the range from 100V AC to 5kV AC with a
resolution of 10V. The maximum total output current is 15mA.
The Sentry 20/25 AC/DC Hipot Testerhas 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
100V DC to 6kV DC 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 Testerhas all of the features of the Sentry 10/15
and 20/25 plus measurement of insulation resistance. The IR measurement range is from
Ω to 10GΩ with test voltages from 50 to 1000V DC.
10M
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 and safe discharge.
Ground ContinuityCheck:All of the Sentry units have a ground continuity check fea-
ture 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.
