The Keysight N3304A (formerly Agilent) is a 300 W, 0-60 V, 0-60 A DC electronic load module designed for use in the Keysight N3300A and N3301A mainframes. It supports testing and evaluating DC power supplies and components with programmable constant current (CC), constant voltage (CV), and constant resistance (CR) modes. The module features highly accurate voltage and current readbacks and takes up a single slot in the mainframe.
