A Solid Foundation for Reliable, Safe and
Practical Safety Compliance Testing.
GWInstek is launching a new safety tester family, the GPT-9900 Series, with 500VA maximum output capacity to the market. The family of
two, including GPT-9904 and GPT-9903, come joining the GPT-9800 series, which carries 200VA output capacity, to serve the market with
higher power demands for the safety tests of electronic products and components. The GPT-9000 Series supports the major test items
among all the needed for the compliance of the safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety regulations.
The GPT-9900 Series is built upon a platform of AC 500VA maximum power output. The GPT-9904 is a 4-in-1 model capable of performing
AC withstanding, DC withstanding, insulation resistance and ground bond tests, whereas the GPT-9903 is a 3-in-1 model capable of
performing AC withstanding, DC withstanding and insulation resistance tests. The GPT-9900 Series safety tester follows every good feature
and advantage of the GPT-9800 Series. The high-efficiency PWM amplifier is the core of GPT-9900 Series platform design to impede the
influence from the voltage fluctuation of input AC source. The output voltage is automatically cut off (within 150μs) upon the detection of
an abnormal output voltage or a trip of current limits during test to protect the operator from hazardous injury. The GPT-9900 Series
automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.
Following a tidy and easy-to-use design concept, the GPT-9900 Series is equipped with a simple & clear panel layout, a high resolution dot
matrix LCD display, and color LED indicators, allowing operators to interpret measurement results easily and quickly. In the role as the
complement of 200VA safety testers, the GPT-9900 Series is designed upon a higher power platform to enhance all major test functions,
including AC withstanding (AC 5kV/100mA), DC withstanding (DC 6kV/20mA), insulation resistance (DC 50V ~ 1000V/50GΩ max.) and
ground bond (AC 32A max./650mΩ max.) tests, with high-power measurement capabilities. Further more, the test duration, ramp up time
and upper/lower limits of the output voltage are fully-adjustable to accommodate a wide variety of safety tests with accurate measurement
results. The “Sweep” function of the GPT-9900 Series is able to display the test results point by point all through the testing period to form
a trace graph. This graphic display performs the characteristic verification of a DUT through observing the parameter response to the
changes of the applied voltage or current or testing time. On the graph a movable marker is available to get the parameter reading on the
specific point of user's interest.
Other significant functions and features of the GPT-9900 Series include the rear panel output for system applications, the open-circuit
detection to ensure proper connections of apparatus for ground bond test, 100 sets of memory to save and recall the panel settings for
individual or sequential tests, a remote output on-off terminal in the front panel and a signal I/O port in the rear panel provided as the
means for remote start/stop control of the safety tester, and RS-232C, USB and GPIB (optional) interfaces available for PC remote control
and test result logging.

The GPT-9900 Series has a unique sweep function to show the trace graph
of test results of the device under test. The test readings are recorded
point by point according to the setting of the applied test voltage or
current and the testing duration (ramp-up time + timer) to form a trace
of parameter response. On this sweep graph, users can use a moveable
cursor to locate the point of specific time or specific amount of applied
source (voltage or current) within test period to know the measurement
result of this point. It helps users to verify the changes of measured
parameter (current or resistance) all thorough the test process, instead
of just obtaining one final value at the end.
Unlike the conventional safety tester design that uses variable voltage
transformer and class AB amplifier to provide testing voltage, the GPT9900 Series, carrying a high-efficiency PWM amplifier design, generates
output source up to 98% efficiency. This greatly reduces the amount of
power loss to heat and therefore lowers the temperature within the
cabinet of the GPT-9900 Series. The suppression of temperature rise
during heavy-duty operations of the tester significantly increases its
reliability and service lifetime. In addition, as PWM amplifier is
comparatively more resistant to the fluctuations of input power voltage,
a stable high-voltage output with less than 1% regulation is provided by
the GPT-9900 Series to perform precision tests of the DUT.
C.
HIGH ACCURACY AND HIGH RESOLUTION TESTING PERFORMANCE
High Adjustment & Measurement Resolution
In order to provide high accuracy testing for production test, regulation
regulations need an AC source for ground bond testing, the GPT-9900
compliance, and characteristic verification, the withstanding test voltage
Series provides 6Vac voltage (open circuit) and 3A~32Aac current for

while the current measurement can be done with 1μA resolution and
SENSE H and SOURCE L terminals) for ground bond test is also

Zero-Crossing Operation
Output Voltage Variation in One Test Cycle
Once the GPT-9900 Series is turned on, the protection functions to
protect operator and DUT are always in operation throughout the testing
period. When the power is turned on, the GPT-9900 Series immediately
goes through the self-check procedures to ensure that all test functions
are performed under normal conditions, as the first protection function
being applied.
at power-on and avoid flashover or arcing phenomena that could affect
the test results, the GPT-9900 Series has a Zero Crossing Turn-On feature,
which ensures the output always starts from the zero crossing of a sine
wave. Moreover, the adjustable voltage ramp-up time (0.1s ~ 999.9s)
allows the test voltage to slowly rise to the set test voltage to reduce the
risk of damaging DUT during mandatory production testing.
The second protection function is activated once the “Start” (output)
button is pressed. At the first moment of start up, the GPT-9900 will
send a detection voltage (~100V) during the initialization period (100ms)
to check whether the DUT has any short circuit due to poor insulation
before the high voltage is applied. This is to prevent high voltage or
current from returning to the DUT during the test time. To protect DUT
from insulation breakdown caused by the rapid increase of test voltage
Furthermore, after the voltage has ramped to the set test voltage, the
GPT-9900 will continue monitoring the voltage and cut off power output
once any irregularity is detected. This provides both the safety tester and
the operator with a high level protection, which allows the test to be
done in a safe and accurate manner.
E.
MULTIPLE PROTECTION MECHANISMS
Safety Interlock
The GPT-9900 Series also offers multiple protection designs to ensure
operator safety in operating the safety tester. The interlock function
provides the hardware key protection for voltage output. When the
interlock function is activated, the testing voltage will present at the
output ONLY when the dedicated interlock key is attached to the Signal
I/O port on the rear side. When the test is not intended to executed,
removing the interlock key can inhibit the voltage output to prevent the
hazard of high voltage output. Except connecting with the key, two
inputs of the Signal I/O port can be connected alone to a senor switch
F.
installed in safety test system. If there is any unexpected object is
detected to intrude into the system, the output is disabled and thus
prevents the operator from exposure to hazardous voltages/currents.
In addition, the GPT-9900 Series can quickly cut off the high voltage
output within 150µs when the test has completed, the high/low limits
have been reached or the emergent stop caused by an abnormal
situation. Lastly, when a test has stopped, the unit also automatically
discharges the voltage across the DUT to reduce the risk of injury to
operator.
FRIENDLY USER INTERFACE
High Intensity Indicators
The 240 x 64 LCD displays not only the setting parameters but also the
test conditions, measurement values and DUT inspection results (PASS
or FAIL) in a legible pattern. The LED indicators in different colors alert
the operator to the status of the safety tester to avoid any possible risk.
G.
Fast Cutoff in 150µs
Large LCD and Function Keys
For example, the status indicator sitting above the high voltage output
terminal will automatically blink when a high voltage presents at output.
In addition, the function keys arranged below the LCD display provide
convenient operation that test setup can be easily done by fewer key punches.

AUTO Testing include Multiple MANU Processing
In order to comply with all safety regulations, the GPT-9900 series also
offers a large number of memory locations (100 sets in total) to store a
variety of test conditions. When a test condition is saved to one of the
100 fixed memory locations, a unique test file name (up to 12 characters)
can also be assigned to its memory location. For example, the test file
name “IEC61010AH” (IEC61010 AC Withstanding test) can saved and
recalled for future use. Any test conditions that have been previously
stored can be used for a single test or combined together for automatic
testing- eliminating the need to perform a series of tests manually.
In addition to using the START/STOP buttons on the front panel to
control the safety tester, the GPT-9900 Series also provides a remote
terminal for connection to an external remote controller and a signal I/O
port on the rear panel for connection to a PLC interface for actuator
control. Furthermore with RS-232C and USB as standard (GPIB optional)
for all the models in the GPT-9900 Series, retrieving test data and results
is convenient via a PC connection.
