The GPT-12000 Series from GW Instek was specifically designed for users who require reliable safety testing in a compact and energy-efficient format. It offers the same advanced technology and safety architecture as the more powerful GPT-15000 Series, but with a 200 VA output power – ideal for laboratory, development, and manufacturing environments with moderate testing requirements.
All models in the series comply with the international safety standard IEC 61010-2-034 and ensure maximum user safety through double insulation, audible and visual warning mechanisms, and automatic discharge of the test object after each test. Modern PWM amplifier technology ensures stable high-voltage output even with fluctuating mains voltage.
The safety analyzers of the GPT-12000 series are used in many industries, including:
- Final testing of electrical devices and components
- Quality assurance in the electronics and manufacturing industries
- Testing of power supplies, transformers, and lighting systems
- Research and development of electrical assemblies
- Type testing and safety verification according to IEC, EN, UL, CSA, GB, or JIS standards
The GPT-12002 model presented here is the versatile all-rounder of the GPT-12000 series and performs AC and DC withstand voltage tests as well as continuity tests. It is ideal for applications requiring both AC and DC voltage testing, such as in the development and production of power supplies, motor controls, or electronic assemblies.
Advantages of the GPT-12002:
- AC/DC combination testing: ideal for mixed test environments with AC and DC voltage
- AC output up to 5 kV / DC output up to 6 kV: high flexibility for various test requirements
- Output power: 200 VA for stable and reproducible measurements
- Precise measurement resolution: 1 μA (ACW) / 0.1 μA (DCW)
- Automatic discharge: Discharge of the DUT to approx. 30 V after each test
- Intuitive operation: 7" TFT color display with clear menu structure and status indicator
- Individually adjustable ramp-up/ramp-down time: for gentle voltage ramp-up
- Safety-oriented design: double insulation, recessed START button, and audible warning
- USB data storage: test results can be exported directly to a USB flash drive
Differences within the series: While the GPT-12001 offers only AC testing, the GPT-12002 expands its functionality to include DC withstand voltage tests. It thus provides a flexible solution for applications where both AC and DC voltage testing are required. Unlike the GPT-12003 (including insulation resistance testing) and GPT-12004 (including ground bond testing) models, the GPT-12002 focuses specifically on voltage and continuity testing.
Product features of the GPT-12000 series:
