The GPT-12000 Series from GW Instek combines the highest testing precision with a space-saving design and was developed specifically for manufacturers, testing laboratories, and quality control departments that need to perform reliable safety tests in accordance with international standards. With an output power of 200 VA, it offers professional testing capabilities in a compact format—ideal for development and production environments with limited space.
All models in the series meet the requirements of the IEC 61010-2-034 standard and offer maximum user safety through double insulation, visual and audible warning signals, and automatic discharge of the test object after each test. The modern PWM amplifier technology guarantees stable high-voltage outputs and reproducible measurement results even with fluctuating mains voltage.
The devices of the GPT-12000 series are suitable for a wide range of applications, particularly in:
- Final testing and quality assurance of electrical devices and assemblies
- Testing of power supplies, transformers, motors, and lighting systems
- Type testing and safety verification according to international standards (IEC, EN, UL, CSA, GB, JIS)
- Research and development in electrical engineering and electronics
- Safety testing during production in the mass production process
The GPT-12004 model presented here is the most comprehensive model in the GPT-12000 series and combines AC/DC withstand voltage tests, insulation resistance tests, ground bond tests, and continuity tests in a single device. It thus covers the entire spectrum of safety testing requirements and is particularly suitable for production environments where full safety certifications are required.
Advantages of the GPT-12004:
- Four combined test functions: AC/DC withstand voltage, insulation resistance, ground bond, and continuity
- AC output voltage: up to 5 kV / DC output voltage: up to 6 kV
- Ground bond test current: up to 32 A AC for precise grounding tests
- Output power: 200 VA for compact yet powerful testing
- High measurement resolution: 1 μA (ACW) / 0.1 μA (DCW)
- Insulation resistance test: 50 V – 5000 V DC, resolution 0.1 MΩ
- Automatic discharge: Discharge of the test object to approx. 30 V after test completion
- Intuitive operation: via 7" TFT color display with clearly structured menu navigation
- Safety design: double insulation, audible/visual warning indicators, recessed START button
- USB data storage: Convenient export of test results without a PC
- Flexible test parameters: Ramp-up/ramp-down time, limit values, and timers can be set individually
Differentiation within the series: The GPT-12004 is the top model of the GPT-12000 series. While the GPT-12001 is designed for AC testing, the GPT-12002 for AC/DC testing, and the GPT-12003 additionally for insulation resistance testing, the GPT-12004supplements these functions with the powerful ground bond test – thus offering a complete safety testing solution in a single device.
