GWINSTEK GPT-9800 Series (GPT-9801, GPT-9802, GPT-9803, GPT-9804) Safety Tester

Compliance, Safety, Reliability

The GPT-9800 Series safety testers combine high-stability testing, safety-focused design, and a fresh new look. Their functions meet the testing requirements of safety regulations such as IEC, EN, UL, CSA, GB, and JIS for a wide range of electronic and electrical products and components.

Choose the Model That Fits Your Needs

The GPT-9804 is a 4-in-1 model offering AC/DC withstand voltage testing, insulation resistance testing, and AC ground bond testing.

The GPT-9803 provides AC/DC withstand voltage testing and insulation resistance testing.

The GPT-9802 provides AC and DC withstand voltage testing.

The GPT-9801 provides AC withstand voltage testing.

High-Stability Output
All models in the series deliver 200 VA AC output and use a high-efficiency PWM amplifier to effectively suppress the effects of input voltage fluctuation and waveform distortion, ensuring a stable high-voltage output to the device under test during AC withstand voltage testing.

Comprehensive Protection Design

With safety in mind, the GPT-9800 Series uses combined software and hardware control to provide power-on self-test, zero-start, detection of abnormal output voltage during testing, and rapid output cutoff (150 μs) when the upper/lower limits are exceeded. It even requires a special interlock terminal to be connected before the safety tester will output. In addition, automatic discharge (200 ms) is performed after each test to prevent excessive test voltage from remaining on the device under test and posing a hazard to the user.

 For operation, observation, and measurement performance, the GPT-9800 Series features a streamlined keypad, a highly legible dot-matrix blue LCD, and high-brightness LEDs in different colors as status indicators, making setup and measurement reading easier and more intuitive.

The core test functions include AC withstand voltage testing (AC 5 kV/40 mA), DC withstand voltage testing (DC 6 kV/10 mA), insulation resistance testing (DC 50 V–1000 V/9500 MΩ), and ground bond testing (AC 30 A max./650 mΩ), together with output adjustment resolution, measurement resolution, voltage ramp time settings, and upper/lower limit judgment settings, enabling users to perform the required tests and obtain accurate measurement results. 

Additional features of the GPT-9800 Series include: open-circuit detection (for ground bond testing only) to prevent misjudgment of measurement results caused by broken connections; 100 memory groups for storing different test conditions; automatic continuous testing by combining multiple memory groups; front-panel remote terminal and rear-panel Signal I/O for convenient, application-specific control of tester output/stop. For users who need computer control and test result logging, RS-232C, USB, and GPIB (optional) interfaces are also available.
