Keysight (Agilent) N6783A-BAT 8 V, 3 A, 24 W battery charge/discharge module

The Keysight N6783A-BAT is a 2-quadrant battery charge/discharge module engineered for the N6700 modular power system family. It functions as both a programmable power supply (CC/CV charging mode) and programmable electronic load (CC discharging mode), enabling comprehensive battery validation testing. The module delivers 8 V at currents ranging from −2 A to +3 A with 24 W maximum power. A high-speed digitizing measurement system captures voltage and current data at 20 µs intervals using a 50 kHz digitizer, supporting both transient and steady-state battery analysis. When integrated with the N6705B DC power analyzer mainframe, engineers can condition batteries across variable charge states and validate performance against design specifications under realistic operating conditions.
