Electrical safety testing is one of the major
item in th e el ectri cal product qua lity tests.
All electrical products consisting of adapter,
SMPS, charger, house appliance, information
te chnology product and vid eo produ ct are
required to perform electrical safety tests.
The 19032 seri es combines Hi-Pot, IR, GB,
LC/ALC/DLC and Dynamic Function Test. That
can save 50% of production line space without
purchasing several Hi-Pot testers , 19032 is
able to increase efficiency of electrical safety
test during manufacturing and reduce the risk
on testing.

TWINPORT
The 19032 electrical safety tester has Twinport™ Technology. This patent and
unique feature are allow to test Hi-pot and ground bond simultaneously. It can
reduce half of the time on testing;so it is ideal for production test.

FLASHOVER DETECTION
The 19032 has Flashover Detection as other Chroma safety test series. Flashover is electricity transient or non-sequential discharge generated by
the inner or surface of insulation component which cause DUTs to lose original insulation feature,generated carbonation electrically conductive path
and damages the product . Test voltage or shift rate of leakage current is required. As ashover cannot be detected by leakage current, Flashover
Detection is one of inevitable inspection items in HV test.

OPEN / SHORT CHECK (OSC) (PATENT 254135)
OSC function is used to check if the connection is open (bad contact) or short (DUT short) during the test procedure. When circuit opened during
the test, NG product will be judged as good product. When short occurred during the test, screening earlier can reduce the damage on equipment .
Generally speaking, the DUT has capacitive load (Cx) from tens of pF to several uF in normal state. A micro capacitance will occur on an open
circuit interface, once the connection is interrupted (as Cc in gure 2). In general, the capacitance is lower than 10pF ; thus the total capacitance is
far lower than the normal product. The capacitance is far higher than normal when the DUT short or close to short. Therefore, users can judge the
short problem by using the high/low limit value of capacitance change.

CAPABILITY OF CONTROLLING CHROMA AC SOURCE (6400 / 61600 / 61500 SERIES)
The manufacturers apply Chroma AC Source as the power supply to increase the input voltage stability for
dynamic leakage current test. The 19032 uses RS232 interface to control the AC Source related models that
make the dynamic leakage current test more convenient.
GFI HUMAN PROTECTION (19032-P)
The ultimate purpose of safety testing is to protect users from electric hazard.The
19032-P also has GFI function to protect the operator. GFI function can cut off the power
output immediately while human body is suffering electric shock. GFI function detects the
current from Earth GND (Ioperator) and LOW terminal (Idevice). The voltage output will
be cut off if the current is over 0.5mA.
FLOATING CIRCUIT FUNCTION (19032-P)
For the opoerator to using the Safety Test Instrument more safely, Chroma invented
Floating circuit which is based on the leading technology. Under Floating status, the
grounding leakage current will not exceed 3.5mA no matter what the withstand voltage
If the person touches any terminal. It complies with EN50191 for outputting to ground
terminal within current limit and for protecting the operator from electrical to injury.

SUPPORT TOUCH CURRENT / LEAKAGE CURRENT TEST
The current brimmed after ow through insulation resistance,
is called as Leakage Current. When the leakage current goes
through human body, the current flows to Earth via human
body ,which can cause electric damage. The leakage current
is testing under operating state. A human body RC network
will be added in leakage current test, it can simulate the value
of leakage current in real condition.
Th e lea ka ge current has d ifferent testing m odes an d
standards in accordance with different safeties and test
points. The most often seen current tests are Earth Leakage
Current, Patient Leakage Current and Patient Slave Leakage
Current.
The 19032 is used with different dynamic leakage current
modules and human body simulation equivalent circuit for
the requirements of various safety modules. It can apply to
Electrical Safety Testing for Household Appliance, Video
Product, Medical Equipment and etc.

500VA HIPOT TEST (19032-P)
The High Limit of Hipot test currently is often from 5 to 10mA. However, there is still a few DUTs such
as Safety Integrated Analyzer of EMI Filter or large-sized motor require massive power. The 19032-P
enhances the power of 19032 largely to equip the capabilities of outputting and measuring AC 100mA/

To integrate the high charge current with other safety tests as any integrated analyzer for the
users to use higher leakage current or large-sized electrical safety equipment. This brings the best
efciency to production line and quality assurance.
The design of 500VA also complies with the requirement of IEC/UL output power to add the
selection function of "no protection for trip circuit under short current 200mA and 100mA".
