GPT-9903A

The GPT-9903A is a GPT-9900 series A.C. 500VA AC/DC withstanding voltage/insulation tester. It is capable of performing both AC and DC withstanding tests. The high efficiency PWM amplifier is the core of GPT-9903A 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-9903A automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.
