GPT-9802

The GPT-9802 from GW Instek is a GPT-9800 series A.C. 200VA AC/DC withstanding voltage tester. It is capable of performing both AC and DC withstanding tests. The GPT-9802 is built upon a high efficiency PWM amplifier platform with AC 200VA maximum output capacity to impede influence from voltage fluctuation of input AC source. A self check is performed to make sure all the functions and operations are under normal condition each time when the tester is turned on, the zero crossing turn-on design imposes output voltage to always begin at zero crossing of a sine wave to avoid impact of surge voltage output and output voltage is automatically cut off (within 150µs) when abnormal output voltages have been detected or when the upper or lower current limits have been reached during testing. The GPT-9802 tester is equipped with a simple & clear panel layout, high resolution dot matrix LCD display and colour LED indicators, allow operators to interpret measurement results easily and quickly.
