AC/DC Withstanding Voltage/Insulation Resistance/Ground Bond Tester
The GPT-9804 meets a variety of safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety-related requirements for the safety tests of electronic products and components.

The GPT-9804 is a 4-in-1 model capable of performing AC withstanding, DC withstanding, insulation resistance and ground bond tests. The GPT-9804 is built upon a high-efficiency PWM amplifier platform with AC 200VA maximum output capacity to impede the influence from the voltage fluctuation of the input AC source. This ensures a stable voltage supply for all the tests of the GPT-9800 Series.

Targeting user's protections, the GPT-9804 uses a combination of hardware and software controls to improve safety: A self-check is performed to make sure all the functions and operations are under normal condition each time when the tester is turned on; the Zero Crossing Turn-On design imposes the output voltage to always begin at the zero crossing of a sine wave to avoid the impact of surge voltage output; and the output voltage is automatically cut off (within 150μs) when abnormal output voltages have been detected or when the upper or lower current limits have been reached during testing. To protect operator from hazardous injury, the GPT-9804 automatically discharges the DUT after test (within 200ms) each time to eliminate excessive voltage that remains on the DUT. To further ensure safety, the interlock connector can also be used as double protections to prevent inadvertent operation.

The GPT-9804, equipped with a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators, allows operators to interpret measurement results easily and quickly. All major test functions, including AC withstanding (AC 5kV/40mA), DC withstanding (DC 6kV/10mA), insulation resistance (DC 50V to 1000V) and ground bond (AC 30A max.) tests, are performed under a high-stability voltage output with high-resolution measurement results. 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.

Other functions and features of the GPT-9804 include: open circuit detection for ground bond testing to get correct measurement result with confidence; 100 sets of memory to save panel settings, which can be recalled for single test individually or for automatic tests in sequence; 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; RS-232C, USB and GPIB (optional) interfaces available for PC remote control and test result logging.
