Agilent/Keysight RP7963A

The Keysight RP7963A is a 10 kW single-output bidirectional regenerative DC power supply engineered for electronic test and measurement applications. Operating in two-quadrant mode, it functions as both a power source and regenerative electronic load, enabling seamless transitions between sourcing and absorption without interruption. This dual capability addresses demanding requirements in energy storage device testing, converter validation, and battery characterization where precise control over power delivery and energy recovery is essential.

The RP7963A employs autoranging output characteristics to deliver an expanded power curve across voltage and current combinations beyond traditional rectangular supplies. This flexibility supports accurate emulation of various battery states, internal resistances, and charge conditions for comprehensive battery life characterization and early failure detection. Its regenerative design recovers up to 90% of energy to the grid, reducing operational power consumption and cooling requirements.
