The Keysight RP7983A is a bidirectional regenerative DC power system engineered for high-demand testing in automotive and energy applications. Operating as both a precision power source and electronic load, it delivers 30 kW across a 2000 V, ±30 A output range with sub-millisecond command response. Two-quadrant operation enables seamless transitions between sourcing and sinking current, with regenerative capability returning up to 90% of absorbed energy to the grid—reducing operational costs for electricity and cooling.
