GW Instek GPT9901A Withstanding Voltage/ Insulation Resistance

GW Instek GPT9901A Withstanding Voltage/ Insulation Resistance supports 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.

GPT-9901A AC 500VA AC Withstanding Voltage Tester is built upon a platform of AC 500VA maximum power output. The GPT-9901A AC 500VA AC Withstanding Voltage/ Insulation Resistance Tester follows every good feature and advantage of the GPT-9900 series. The high-efficiency PWM amplifier is the core of GPT-9901A 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. The GPT-9901A automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.

Following a tidy and easy-to-use design concept, the GPT-9901A is equipped with a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators, allowing operators to interpret measurement results easily and quickly. In the role as the complement of 200VA safety testers, the GPT-9900 series is designed upon a 500VA output platform to enhance all major test functions, including 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 of the GPT-9901A AC 500VA AC Withstanding Voltage Tester is able to display the 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.
