Atec Chroma-19050-19070 Series - Manual

GPIB RS-232 PRINTER
AC/DC/IR Hipot Tester
Complete Dielectric Testing Solution
The 19050 series electrical safety testers 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 Chroma Hipot Tester 19050 series provides
3 models for choice. The 19052 is for AC/DC/IR
Hipot testing and insulation resistance (IR)
measurements. The 19053 IR measurement is with
8 scan channels, and the 19054 IR measurement
is with 4 scan channels capability into a single
compact unit.
The Chroma Hipot Tester 19070 series provides
2 models for choice. The 19071 is for AC Hipot
testing. The 19073 combines both AC and DC
Hipot with insulation resistance (IR) measurements
into a single compact unit.
Open Short Check (OSC)
The OSC function is used to check whether the
connection is open circuit between instrument
and DUT or breakdown inside DUT before testing
the electrical safety.
Flashover (ARC) Detection
The 19070 series is sensitive enough to monitor
current spikes even if they do not exceed the
maximum trip current level.
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 Interrupt (GFI)
GFI is required by the National Electrical Code
in wet locations. Such devices automatically
interrupt power when a ground current > 0.5mA
existed for more than a few milli-seconds to
protect users.
Quick Discharge
In DC hipot and IR test the device under test is
discharged back through the HV transformer. This
technique results in a rapid and safe discharge.
