The GW Instek GPE-X323 Series is a family of economical linear DC power supplies covering output power from 192 W to 217 W across four models. The series includes the single-output GPE-1326, dual-output GPE-2323, three-output GPE-3323, and four-output GPE-4323, giving electronics labs a consistent control interface and form factor whether powering a single rail or a multi-rail device under test. Each member of the series uses a linear regulation topology and a 4.3-inch LCD with digital panel control to replace the conventional knob-and-analog-meter approach found in older bench supplies.

The GPE-X323 Series is positioned for laboratory and educational facilities, product testing and quality assurance benches, service operation and post-sales support, and product development and debugging. The independent isolated outputs allow each channel to bias separate sections of a DUT without ground-loop coupling, while the tracking series and parallel modes on the multi-output models extend the voltage and current envelope of the instrument when a single higher-power rail is needed.

Brand Heritage

GW Instek is the brand of Good Will Instrument Co., Ltd., headquartered in New Taipei City, Taiwan and founded in 1975. The company maintains subsidiaries in the United States (Instek America Corp.), China, Malaysia, the Netherlands (Good Will Instrument Euro B.V.), Korea, and Japan (operating as Texio Technology Corporation). The GW Instek name has been used continuously since the company's founding and has not been subject to acquisition or rebranding.

Compare Other Models in This Series

The GPE-X323 Series is a four-model family of linear multi-output DC power supplies sharing a common chassis, control interface, and regulation architecture. The four models differ primarily in channel count, total output power, and the specific voltage and current envelope of each channel — letting a customer choose the model whose channel mix matches the DUT without changing operating procedures across the lab.

All four models share the same 4.3-inch LCD display, digital panel control, Set View and Key Lock functions, smart cooling fan, and Remote I/O analog On/Off interface. The GPE-2323, GPE-3323, and GPE-4323 add tracking series and parallel operation between their first two 0–32 V / 0–3 A channels, while the GPE-1326 provides a single 0–32 V / 0–6 A output without tracking modes.

Each model in the GPE-X323 Series is its own product page on valuetronics.com with new-matched pricing and inventory. The links in the comparison below take you to the page for that specific model so the buying decision is on one canonical destination per part number.

The four models partition the family by channel count and total power. The GPE-1326 is the single-channel entry at 0–32 V / 0–6 A (192 W) for benches that need one higher-current rail. The GPE-2323 doubles that to two independent 0–32 V / 0–3 A channels (192 W total) and adds tracking series and parallel operation for applications that occasionally need 0–64 V or 0–6 A from the combined pair. The GPE-3323 keeps the two programmable 0–32 V / 0–3 A channels and adds a fixed 5.0 V / 5 A logic-supply channel (217 W total), and the GPE-4323 carries four channels — two 0–32 V / 0–3 A and one each of 0–5 V / 0–1 A and 0–15 V / 0–1 A — for 212 W total when a wider mix of rail voltages is needed from one chassis.

Refer to the comparison table that follows for the per-channel voltage, current, tracking-mode, and total-power specifications side by side. Other parameters — regulation, ripple, metering resolution and accuracy, insulation, environmental ratings, and AC input — are shared across the family per the datasheet specifications table.
