"The GPT-900 series is built upon a platform of AC 500 VA maximum power output. The high efficiency PWM amplifier is the core of GPT-9900 platform, designed to impede the influence from the voltage fluctuation of input AC source. Output voltage is automatically cut off (within 150 us) upon the detection of an abnormal output voltage or a trip of current limits during test. The GPT-900 series automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT. The tester is equipped with a simple and clear panel layout, a high-resolution dot-matrix LCD display and colour LED indicators. Measurements can be interpreted easily and quickly.500 VA AC Test Capacity. 240 x 64 Ice Blue Dot-Matrix LCD. Sweep function for DUT characteristic analysis.
