GW Instek GPT ACDC Withstanding Voltage. Insulation and Ground Bond Testers GW Instek GPT 9801, This GPT 9801 AC withstanding voltage tester from GW Instek provides a solid foundation for reliable, safe and practical safety compliance testing. Manufactured with high durability and multiple user protection design, the GPT 9801 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, including an AC withstanding test. 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, ensuring a stable voltage supply for all the tests. Targeting user's protections, the GPT 9801 uses a combination of hardware and software controls to improve safety A self check is performed to make sure all 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 the output voltage is automatically cut off within 150956s 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, this quality voltage tester 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 9801 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 5kV40mA are performed under a high stability voltage output with high resolution measurement results. Additionally, the test duration, ramp up time and upperlower 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 9801 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 IO port in the rear panel provided as the means for remote startstop control of the safety tester RS 232C, USB and GPIB optional interfaces available for PC remote control and test result logging.
