The Keysight RP7962A is a 10 kW regenerative DC power supply operating at 500 V and ±40 A with bidirectional power flow capability. This two-quadrant system functions simultaneously as a precision power source and electronic load, enabling seamless transitions between sourcing and sinking current without output disruption. The unit accepts three-phase AC input from 400 V to 480 V (±10 %) and recovers 90% of power back to the grid, reducing energy waste and cooling requirements.
Autoranging output expands the voltage-current envelope beyond traditional fixed-ratio supplies, maximizing flexibility across diverse test scenarios. An integrated arbitrary waveform generator produces user-defined transient profiles up to 65,535 data points, while battery emulation mode simulates realistic charge states and internal resistance for high-voltage battery characterization. Programmable output resistance to 50 Ω and continuous current sinking at full rated capacity enable comprehensive power converter and energy storage validation.
