Taipei, Taiwan – 10 September 2025 – Global leader in electronic test and measurement instruments, GW Instek (Good Will Instrument Co., Ltd.), proudly announces the release of its GPP-1000 Series High-Precision Programmable DC Power Supplies. Combining high resolution, flexible functionality, and comprehensive safety protection, the GPP-1000 Series is designed for R&D, testing, and production environments, delivering stable and efficient power solutions for a wide range of applications.

High-Precision Output for Versatile Applications

The GPP-1000 Series offers up to 1 mV / 0.1 mV voltage resolution and three selectable current resolutions, with maximum accuracy down to 1 μA / 0.1 μA. This ensures precision even in the most demanding measurement scenarios. Supporting both Constant Voltage (CV) and Constant Current (CC) modes, as well as a switchable power supply/electronic load function, the series is suitable for a variety of testing environments. Two models are available: the GPP-1205 (20 V / 5 A / 100 W) and the GPP-1323 (32 V / 3 A / 96 W), offering users flexible output power configurations.

Enhanced Functions for Efficiency and Convenience

The GPP-1000 Series is equipped with Remote Sense design, which automatically compensates for voltage drops caused by lead resistance, ensuring precise output. Built-in data collection and logging functions allow engineers to capture and analyse test data effectively. For higher power requirements, the series supports up to four units in series or parallel, significantly expanding flexibility for applications such as battery packs and power systems.

Additional advanced features include sequence programming output, voltage and current slew rate control, and output delay settings, enabling engineers to simulate different real-world conditions and perform more comprehensive verification during product design.

Comprehensive Safety Protection

To ensure secure operation, the GPP-1000 Series integrates multiple protection mechanisms, including Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP), and reverse polarity protection. A front panel lock function further prevents accidental operation, safeguarding both equipment and personnel during testing.

Flexible Interfaces and Intelligent Cooling

The GPP-1000 Series supports USB-TMC/CDC, LAN, and optional GPIB interfaces, meeting requirements for remote control and automated testing environments. Featuring a 2.4-inch TFT-LCD colour display with three screen modes, data is presented clearly and intuitively. In addition, an intelligent temperature-controlled fan reduces noise while ensuring efficient cooling, enabling long-term stable operation.

Wide Range of Applications

With its high precision and multifunctional design, the GPP-1000 Series is particularly suited for:

1. Scientific research and experimental testing

2. Battery charge and discharge tests

3. Applications requiring low-noise and stable voltage output

4. Electronic component measurement

5. Testing of 3C consumer electronics

Conclusion

Thanks to its high resolution, versatile communication interfaces, comprehensive safety protections, and flexible application modes, the GW Instek GPP-1000 Series not only raises the benchmark for conventional power supplies but also reflects the direction of modern test equipment development—making testing processes more accurate, convenient, and efficient. Whether in R&D laboratories or production testing, the GPP-1000 Series stands as a reliable power solution for engineers worldwide.
