A Solid Foundation for Reliable, Safe and Practical Safety Compliance Testing
Part of the GPT-9800 series, the GPT-9902A is capable of performing both AC and DC withstanding tests. The high-efficiency PWM amplifier is the core of GPT-9900 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-9902A 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-9902A 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.
The GPT-9900-Series' unique sweep function shows the trace graph 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 (rampup time + timer) to form a trace of parameter response.
Other significant functions and features of the GPT-9902A include rear panel output for system applications, 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, 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.
