The Instek GPT-9903 AC 500VA AC/DC Withstanding Voltage/ Insulation Resistance Tester 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.

The high-efficiency PWM amplifier is the core of Instek GPT-9903 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. It automatically discharges the DUT after each test to eliminate excessive voltage that remains on the DUT.
