Keysight's RP7900 Series - Regenerative Power Supplies

The RP7900 Series is Keysight's all new regenerative power supply family, providing both sourcing and electrical loading up to 20 kW. A bidirectional supply is ideal for testing energy storage and converters. A regenerative power supply safely returns the energy to the grid eliminating additional costs to remove the excess heat and therefore avoid measurement errors caused by temperature rise.

The RP7900 devices are able to operate in voltage or current priority. Voltage priority allows positive and negative current limits, which allows the power supply to seamlessly change from sourcing to sinking current. This is especially important when testing energy storage systems.
