The GW Instek GPT-9800 series AC/DC Withstand Voltage Safety Tester are designed to test AC voltages up to 5kVAC/40mA and DC voltages up to 6kVDC/10mA. The dielectric voltage withstand test can provide important insight into the capabilities and limits of a device’s insulation system.
There are a total of 4 safety testers in the GPT-9800 Series, namely GPT-9801, GPT-9802, GPT-9803 and GPT-9804. While the GPT-9801 performs AC Withstand Testing, the GPT-9802 is capable of performing both AC and DC Withstand testing. The GPT-9803 is a 3-in-1 model is designed for AC/DC Withstand and Insulation Resistance Tests, while the GPT-9804 is a 4-in-1 model capable of performing AC/DC Withstand, Insulation Resistance and Ground Bond/ Ground Continuity Testing. Other features of the complete GPT-9800 series include: open circuit detection for Ground Bond/Continuity testing to obtain correct measurement results with confidence; 100 memory locations to save panel settings, which can be recalled for single test individually or for automatic tests in sequence; a remote On/Off output on the front panel, and an I/O port on the rear panel are provided for remote start/stop control. RS-232C, USB and GPIB (optional) interfaces are available for PC remote control and test result logging. LabView drivers are also available for incorporation into ATE systems.
A reliable, safe and practical safety compliance tester, the GPT-9800 series is designed to meet a variety of safety standards such as IEC, EN, UL, CSA, GB, JIS and other requirements for safety testing electronic products and components. The GPT-9800 series of safety testers uses a combination of hardware and software controls to asses user safety. These safety testers are built on 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.
A self-check is performed each time the tester is turned on, to ensure that all the functions are operating correctly. The Zero Crossing Turn-On design means that the output voltage always begins at the zero crossing of a sine wave to avoid any output surge voltage. The output voltage is automatically disabled (within 150μs) when abnormal output voltages have been detected or when the upper or lower current limits have been reached during testing. To protect operators from hazardous injury, the GPT-9800 Series automatically discharges the DUT after testing (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 a double protection to prevent inadvertent operation.
The GPT-9800 series Safety Tester has a clear and simple panel layout, a high resolution dot-matrix LCD display, and color LED indicators, allowing operators to easily and quickly interpret measurement results. All major test functions are performed under a high-stability voltage output with high-resolution measurement results. 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.
