The Keysight RP7972A is a bidirectional regenerative DC power supply delivering 1000 V at ±60 A with 20 kW maximum power. It operates in two-quadrant mode, functioning simultaneously as a precision power source and electronic load. The unit returns up to 90% of consumed energy back to the grid, reducing operational costs while maintaining fast transient response of 300 μs and sub-millisecond command processing. Built for high-voltage power converter testing in automotive, aerospace, energy storage, and defense applications.
