The GW Instek GPT- 9904 is capable of performing AC withstanding, DC withstanding, insulation resistance and ground bond tests needed for the compliance of the safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety regulations. 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. Specifications.
