The Keysight RP7952A Regenerative Power System is a bi-directional DC power supply and regenerative electronic load designed for high-power battery, converter, and energy storage device testing. Operating across 0–500 V and ±40 A with 10 kW output capacity, this 3U rack-mount system functions simultaneously as both a precision source and load, eliminating the need for separate instrumentation. Two-quadrant operation enables seamless transitions between sourcing and sinking current without output characteristic changes, while regenerative capability returns up to 90% of power to the grid, reducing facility cooling and energy costs.
