The Keysight RP7952A is a bidirectional regenerative power system delivering 10 kW across 0–500 V and ±40 A output. Operating in two-quadrant mode, it functions simultaneously as a DC power source and electronic load, enabling uninterrupted transitions between sourcing and sinking current. The regenerative design returns up to 90% of consumed energy to the grid, reducing cooling and operational costs. Three-phase AC input (200–208 VAC, ±10%) draws 35 A per phase at 0.99 power factor with efficiency exceeding 80% at full power. Output autoranging expands the voltage-current operating envelope. Voltage regulation holds within 30 mV load change; current regulation within 17 mA. Transient response recovers in 500 μs with 1.25 V settling band. Output ripple measures 100 mV RMS and 500 mV peak-to-peak. The compact 3U-high form factor (31.8 kg) integrates into standard racks.
