This GPT-9904 AC/DC withstanding voltage, insulation and ground bond tester from GW Instek provides a solid foundation for reliable, safe and practical safety compliance testing.
Manufactured to meet 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, this is a 4-in-1 model capable of performing AC withstanding, DC withstanding, insulation resistance and ground bond tests.
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. 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 against hazardous injury, the GPT-9904 is automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.
The GPT-9904 is equipped with a simple and clear panel layout, a high resolution dot matrix LCD display, and colour LED indicators, allowing measurement results to be interpreted easily and quickly. All major test functions, including AC withstanding (AC 5kV/40mA), DC withstanding (DC 6kV/10mA), insulation resistance (DC 50V ~ 1000V/50GΩ max.) and ground bond (AC 30A max./650mΩ max.) tests, are performed under a high-stability voltage output with high-resolution measurement results. Additionally, 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 displays 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 functions and features of the GPT-9904 include: 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.
