Keysight (Agilent) N3304A Electronic Load Module, 300 Watt

The Keysight N3304A is a single-channel, 300 W DC electronic load module designed for integration into N3300A or N3301A mainframes. It provides precise testing of DC power sources, power components, and batteries across voltage and current ranges of 0–60 V and 0–60 A respectively. The module operates in constant current, constant voltage, and constant resistance modes, each with selectable ranges and high measurement accuracy. A 16-bit measurement system enables simultaneous voltage, current, and power measurement with waveform digitization capability. Front panel, GPIB, and RS232 interfaces allow full control and read-back, with single GPIB addressing for multi-module configurations. Programmable slew rate control and stable operation from 0 V support dynamic load simulation. The module delivers continuous power with linear derating from 100% at 40 °C to 75% at 55 °C, making it suitable for automated test equipment and battery characterization applications.
