The Keysight RP7935A is a bidirectional regenerative power system that sources and sinks current with seamless transitions between modes. This two-quadrant DC power supply and electronic load delivers 10 kW maximum output power across 0–80 V and ±250 A, making it essential for testing energy storage devices, power converters, and high-speed digital systems. The regenerative design returns up to 90% of power to the grid, reducing energy consumption and cooling requirements. Sub-millisecond command processing and fast output speed enable responsive testing, while autoranging output characteristics expand the voltage and current combinations available in a single 3U rack unit.
