Agilent/Keysight RP7932A

The Keysight RP7932A is a 5 kW bidirectional regenerative DC power supply engineered for high-power test applications requiring seamless transitions between sourcing and sinking current. Operating in two quadrants as both a power source and regenerative electronic load, the unit delivers 0–80 V at up to ±125 A with autoranging output characteristics that expand available voltage and current combinations. Its regenerative design returns up to 90% of power to the grid, reducing energy consumption and cooling costs.
