Keysight Technologies, Inc. (NYSE: KEYS) expands its regenerative power system series with two new models. The models are enhanced with power priority and support power options of 20kW and 30kW at 500V. This allows users to program the output power seamlessly across the zero point when transitioning between positive and negative.
As electric vehicles (EVs) and renewable energy systems continue to evolve, the demand for robust testing equipment is increasingly critical. The 500V models enable engineers to implement higher current and power solutions to support a wider range of applications, including battery-powered solutions in agriculture, residential energy storage, and compact transportation such as e-scooters, e-bikes, and motorcycles.
The Keysight RP7900 series regenerative power system is a family of bi-directional, regenerative DC power supplies with highly integrated safety features. The regenerative capability enables the power normally consumed to be returned to the grid cleanly, saving costs associated with energy consumption and cooling.
The regenerative power system series offers several key benefits, making it a valuable asset for engineers. One of its primary advantages is its ability to enable smooth transitions, allowing seamless switching between sourcing and sinking without disrupting the power supply’s output characteristics. Safety is enhanced through the solid-state output disconnect switch, which provides rapid protection and ensures smooth on/off transitions when faults are detected.
Another key feature is its flexible auto-ranging capability, which allows engineers to work with a wide range of voltage and current combinations using a single power supply, reducing the need to frequently switch equipment to meet changing test requirements. The system also enhances testing speed with a command-processing time of under one millisecond, increasing throughput and boosting overall efficiency. Additionally, its concurrent voltage and current measurement capabilities ensure highly accurate testing, giving engineers the confidence to validate their designs with precision and optimize performance effectively.
Michael Reser, Automotive and Energy Solution EV Segment Director at Keysight said, “The ability to test EV batteries is critical to supporting future innovation. At Keysight we are committed to providing the tools needed to build better batteries faster while ensuring performance and safety. By expanding our product line to test at 500V, we are continuing to deliver on this while supporting a wider range of use cases to keep pace with the rapidly evolving EV market.”
