1. Introduction <\/strong>GW Instek GPT-9803 <\/strong>Electrical Safety Tester<\/strong><\/h2>\n

GW Instek is launching to the market a new series of safety tester\u00a0(hi-pot tester\/hipot tester)\u00a0with high durability and multiple user-protection design. The GPT-9800 Series look to meet a variety of safety standards such as IEC, EN, UL, CSA, GB, JIS and other safety-related requirements for the safety tests of electronic products and components.<\/p>\n

A total of 4 safety testers in the GPT-9800 Series, namely GPT-9804, GPT-9803, GPT-9802 and GPT-9801. The GPT-9803 is a 3-in-1 model capable of performing AC withstanding, DC withstanding as well as insulation resistance tests. The series of safety tester is built upon a high-efficiency PWM amplifier platform with AC 200VA maximum output capacity to impede the influence from the voltage fluctuation of the input AC source. This ensures a stable voltage supply for all the tests of the GPT-9800 Series.<\/p>\n

2. The GPT-9803 uses a combination of hardware and software controls to improve safety<\/strong><\/h2>\n

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 the output voltage to always begin at the zero crossing of a sine wave to avoid the impact of surge voltage output; and the output voltage is automatically cut off (within 150\u03bcs) when abnormal output voltages have been detected or when the upper or lower current limits have been reached during testing.<\/p>\n

To protect operator from hazardous injury, the GPT-9800 Series automatically discharges the DUT after test (within 200ms) each time to eliminate excessive voltage that remains on the DUT.<\/p>\n

To further ensure safety, the interlock connector can also be used as double protections to prevent inadvertent operation.<\/p>\n
