The Keysight RP7933A is a 10 kW bidirectional regenerative power system engineered for precision electronic test and measurement applications. Operating in two-quadrant mode, it functions simultaneously as a power source and electronic load, sourcing and sinking current across 0 to ±800 A at 0 to 20 V without requiring output reconfiguration. Power regeneration returns up to 90% of energy to the grid, reducing operational costs and cooling requirements. The unit delivers sub-millisecond command processing and 400 µs transient response recovery, making it suitable for dynamic load simulation and battery emulation across varying charge states. Housed in a 3U rack form factor, the RP7933A integrates LAN (LXI Core), USB, and GPIB interfaces with seven user-configurable I/O pins for flexible automation and control. Voltage programming accuracy reaches 0.02% + 2 mV; current accuracy is 0.04% + 45 mA. Output ripple remains below 3 mVrms with 30 mV peak-to-peak noise. Load regulation holds 1 mV for voltage and 25 mA for current. Autoranging expands the accessible power curve across voltage and current combinations. Up to 20 identical units may be paralleled to increase output current capacity. AC input requires 200/208 VAC at 35 A per phase, delivering 85% efficiency at full power with 0.99 power factor at nominal conditions.
