GW Instek GPE-1205/1323 Linear DC Power Supply

By Randy Bloom
The GPS-S series - comprising models such as the GPS-1850D, 3030D, and 3030DD—has long been a mainstay among DC power supplies offered by GW Instek. Renowned for its exceptional stability, durability, and dependable performance, this series has earned the trust of users and maintained a steadfast presence in the market for over three decades. Employing linear regulation technology, it delivers low-noise, high-precision output, rendering it well-suited to applications in research and development, education, and electronics manufacturing. Yet, as testing technologies have advanced, certain aspects of the series - namely its resolution, protective features, and user convenience - now present opportunities for refinement. Moreover, the cost of maintenance has steadily risen over time.
To meet the demands of modern testing applications, GW Instek has introduced the GPE-1000 series of DC power supplies as the ideal successor to the esteemed GPS-S series. This new line offers enhanced precision, steadfast stability, and intelligent functionality in its design. The series comprises two models - GPE-1205 (20 V / 5 A / 100 W) and GPE-1323 (32 V / 3 A / 96 W) - providing users with versatile options for output power to suit a range of requirements.
Compared to the old models, the GPE-1000 series has been significantly improved in many aspects. The old model's GPS-S design uses a VR knob, which is not only difficult to adjust the value accurately, but also has a low resolution, usually only up to 100 mV/10 mA. The new model utilizes an Encoder Switch digital knob design, which allows users to set the required value more accurately, and its voltage/current setting resolution is 1 mV/0.1 mA, and the readback resolution is increased to 0.1 mV/10 μA, greatly improving operational convenience and test accuracy. In addition, Remote Sense technology can perform voltage compensation to ensure accurate voltage output. The master-slave series/parallel connection function can provide higher voltage or current, suitable for higher power testing.
In terms of safety, the GPE-1000 series is equipped with multiple protective mechanisms, including Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP), and reverse polarity protection, thereby ensuring the safety of test equipment. Its 2.4-inch TFT-LCD display presents voltage and current readings with clarity, while the front panel lock function prevents accidental operation. Additionally, the temperature-controlled fan design effectively reduces noise, enhancing the comfort of the testing environment.
The GPE-1000 series supports the GRA-441-J/E rack mount kit, facilitating seamless integration into test systems and enhancing both spatial and management efficiency. With its high precision and intelligent design, the GPE-1000 series stands as an ideal choice for research and development, education, and electronics manufacturing. It empowers users to obtain accurate test data, thereby improving the efficiency of product development and testing processes.

The Critical Role of Temperature Uniformity in Industrial Ovens: A W5 Engineering Perspective
Ensure product quality and process repeatability. Learn why temperature uniformity is critical for industrial ovens and how W5 Engineering delivers precision thermal solutions.

Road Load Data Analysis (RLDA) for Structural Validation of Aurora System
W5 Engineering partnered with Aurora to deliver a comprehensive Road Load Data Analysis (RLDA) campaign. Using strain gages, accelerometers, and DEWESoft DAQ, we transformed real-world mechanical loads into actionable data for structural validation and durability assessment.

Rugged Solar-Powered Data Acquisition System for Utility-Scale Tracker Validation
W5 Engineering developed a turnkey, solar-powered data acquisition (DAQ) solution for Nextracker to validate utility-scale solar tracker performance in extreme field environments. Facing the challenge of remote locations with no power infrastructure, W5 integrated DEWESoft KRYPTON hardware and FUTEK load cells into a self-sustaining, IP67-rated ecosystem. The system features a custom-engineered solar power architecture with MPPT charging and battery storage, ensuring 24/7 autonomous operation. By housing high-resolution sensors and a fanless industrial PC within a weather-resistant enclosure, W5 provided Nextracker with the ability to capture high-fidelity structural and load data without the need for grid power or generators—drastically accelerating their engineering validation cycles in the harshest environments on earth.
