GW Instek GPE-1205/1323 Linear DC Power Supply

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 (more info).
