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. The GPT-9801 is able to perform AC withstanding test. 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.
