GPT-9904

GW Instek - GPT-9904 

The GPT-9900 series is the newest safety tester family, with 500VA maximum output capacity to the market supporting the major test items among all the needed for the compliance of the safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety regulations. Specifically, the GPT-9904 is a 4-in-1 model capable of performing AC withstanding, DC withstanding, insulation resistance and ground bond 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. This series automatically discharges the DUT after each test to eliminate excessive voltage that The major test functions includs: AC withstanding (AC 5kV/100mA), DC withstanding (DC 6kV/20mA), insulation resistance (DC 50V ~ 1000V/50GΩ max.) and ground bond (AC 32A max./650mΩ max.) tests, with high-power measurement capabilities. 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. The “Sweep” function is able to display the test results point by point all through the testing period to form a trace graph. The 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 significant functions and features of the GPT-9900 series 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.
