GPT-9902A (GW INSTEK)

The GPT-9902A from GW Instek is a GPT-9900 series A.C. 500VA AC/DC withstanding voltage tester. It is capable of performing both AC and DC withstanding tests. The high efficiency PWM amplifier is the core of GPT-9902A platform design to impede the influence from 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-9902A 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 tester is equipped with a simple & clear panel layout, a high resolution dot matrix LCD display and colour LED indicators allowing operators to interpret measurement results easily and quickly. The sweep function of GPT-9902A is able to display the test results point by point all through the testing period to form a trace gr
