Complete Dielectric Testing Solution
The Chroma Hipot Tester 19050 series provide 3 models for choice. The 19052 for AC/DC/IR Hipot testing and Insulation Resistance (IR) measurements, the 19053 which combines both AC and DC Hipot tests and IR measurements with 8HV scan channel capability into a single compact unit, and the 19054 which combines both AC and DC Hipot tests and IR measurements with 4HV scan channel capability into a single compact unit. Digital display and user friendly control allows test parameters and limits to be set easily without the high voltage activating.
The 19050 series electrical safety tester are advanced digital hipots with load and line regulation to ensure the measurement integrity. Multi-step capability allows users to perform multiple tests in a sequence such as AC hipot followed by IR.
The 19052 AC/DC/IR Hipot Tester performs AC/DC dielectric withstand (hipot) tests. The test of AC voltage can be programmed in the range of 50V AC to 5kV AC with a resolution of 2V. Its maximum total output current is 30mA. The test of DC voltage can be programmed in the range from 50V DC to 6kV DC with a resolution of 2V. The maximum total current is 10mA. The IR measurement range is from 1MΩ to 50GΩ with test voltages from 50 to 1000V DC.
The 19053 AC/DC/IR/SC Hipot Tester has all of the features of the 19052 plus 8HV Scan Channels for multi-point testing.
The 19054 AC/DC/IR/SC Hipot Tester has all of the features of the 19052 plus 4HV Scan Channels for multi-point testing.
In DC hipot and IR tests the device under test is discharged back through the HV transformer. This technique results in a rapid and safe discharge.
Ground Continuity Check
All of the 19050 series testers have a ground continuity check feature to determine the resistance, that is between the ground blade of power cord and any exposed metal on the product, is less than 1Ω.
Ground Fault Interrupters (GFI)
GFI is required by the National Electrical Code in wet locations. Such devices automatically interrupt power when a ground current > 0.5mA exists for more than a few milli-seconds to protect users.
