The Keysight RP7962A is a regenerative power system delivering bidirectional DC power sourcing and electronic load capabilities in a single 3U instrument. Operating across two quadrants, it sources and sinks current without compromising output characteristics while returning up to 90% of sinking power to the grid. This architecture reduces cooling demands and energy consumption, making it ideal for battery emulation, converter testing, and transient characterization in automotive and energy-storage applications.
