The Keysight RP7900 Series regenerative power supply provides both sourcing and electrical loading up to 30 kW. This bidirectional power supply is ideal for testing energy storage systems and power converters. Most electronic loads convert energy into heat, which can cause a temperature rise in a rack leading to measurement errors. A regenerative power supply safely returns energy to the grid, eliminating additional costs associated with removing excess heat.
