The Keysight RP7963A is a 10 kW regenerative power system delivering bidirectional DC power for high-power component and subsystem testing. Operating across two quadrants, it functions simultaneously as a precision power source and regenerative electronic load, sourcing and sinking up to ±20 A at 950 V without output characteristic changes. The system returns up to 90% of power to the grid, reducing operational costs and heat dissipance in demanding test environments.
The RP7963A supports multiple operational modes tailored to automotive and energy storage applications. Battery emulation mode simulates high-voltage batteries with programmable internal resistance up to 50 Ω, enabling characterization of battery operating life and detection of early failures across different charge states. Arbitrary waveform generation produces user-defined voltage or current profiles with up to 65,535 data points. Transient simulation capabilities include step functions, constant dwell arbitrary waveforms, and list sequences up to 512 entries for dynamic load testing.
