GW Instek PEL-3041 Programmable Electronic Load

Overview

The GW Instek PEL-3041 is a single-channel programmable DC electronic load from the PEL-3000 series with 350W capacity (1.5–150V, 0–70A). It features 0.01mA current resolution and a 16A/µs current Slew Rate, making it ideal for testing server power supplies, Switching Power Supplies (SPS), and industrial/commercial computer equipment.

Designed for heavy-duty applications requiring continuous 24-hour operation, the PEL-3041 supports multiple operating modes, sequence functions, and dynamic load simulation. It includes features such as soft start, external analog control, and comprehensive protection functions to meet demanding test requirements.
