The GPT-15000 series from GW Instek was developed for demanding safety tests in the electrical and electronics industry. It combines maximum measurement accuracy, comprehensive protection functions and user-friendly operation - ideal for production, quality assurance and research. The devices in this series are based on the latest PWM amplifier technology, which ensures stable high-voltage output with consistent accuracy, even with mains fluctuations or distorted input signals.
All models comply with the international safety standard IEC 61010-2-034 and feature double insulation, visual and audible warning signals and automatic discharge of the test object after each test. The large 7" TFT colour display ensures clear visualization of the measured values and easy navigation.
The devices in the GPT-15000 series are suitable for a wide range of applications, particularly in:
- Production and final testing of electrical devices
- Quality assurance in industrial electronics
- Type testing and safety assessment in accordance with international standards
- Research and development of power supply units, household appliances and lighting systems
- Testing of medical technology, control units and IT hardware
The GPT-15004 variant presented here is the most powerful model in the GPT-15000 series and combines all essential safety test functions in one device. It enables AC and DC withstand voltage tests, insulation resistance tests, continuity tests and ground bond tests with high test current. It therefore fully covers all test requirements for electrical safety standards and is the ideal solution for complex test environments in series production or product qualification.
Advantages of the GPT-15004:
- Four combined test functions: AC/DC dielectric strength, insulation resistance, continuity and ground bond
- AC output power: up to 500 VA for precise and stable voltage tests
- Ground bond test current: up to 32 A AC for reliable earthing tests
- Insulation resistance test: 50 V - 5000 V DC, resolution 0.1 MΩ
- High measurement resolution: 1 μA (ACW) / 0.1 μA (DCW)
- Automatic discharge: Discharge of the device under test to approx. 30 V after the end of the test
- 7" TFT color display: clear presentation of measured values, statistics and status displays
- Advanced analysis functions: Sweep and statistics function for determining critical points
- Double insulation: maximum safety for user and test specimen
- USB storage: test results can be saved and exported directly without a PC
Differentiation within the series: Compared to the other models in the GPT-15000 series, the GPT-15004 offers the complete range of test functions. While the GPT-15001 is designed for AC testing, the GPT-15002 for AC/DC testing and the GPT-15003 for insulation resistance testing, the GPT-15004 complements these functions with the powerful ground bond test, making it the flagship of the series.
Product features of the GPT-15000 series:
- AC output voltage: up to 5 kV
- DC output voltage (depending on model): up to 6 kV
- Output power: up to 500 VA
- Ground bond test current: Up to 32 A AC
- Insulation resistance test: 50 V - 5000 V DC, resolution 0.1 MΩ
- Measurement resolution: 1 μA (ACW) / 0.1 μA (DCW)
- Test current during continuity test: 100 mA DC
- Individually adjustable ramp-up/ramp-down time
- Automatic discharge of the DUT at the end of the test
- Optical and acoustic warning indicators for test status and results
- Double-insulated power supply for maximum user safety
- 100 memory locations for manual and 100 for automatic test programs
- USB-, RS-232C, optional GPIB or LAN interface
- Statistics and sweep function for analyzing test results
