Keysight RP7942A: Unparalleled Power System for Demanding Applications

The Keysight RP7942A is part of the industry-leading RP7900 Series regenerative power platform engineered for advanced R&D, validation, and production-level testing of energy storage devices, vehicle powertrains, and high-efficiency power conversion systems. Designed for modern electrification requirements, the RP7942A provides precise control and rapid transient response across its full operating range of 80 V, ±125 A, and 5 kW, enabling highly accurate simulation of real-world power conditions.

Engineered for laboratory and automated test environments, this two-quadrant system operates as a programmable DC power source and regenerative electronic load. With regenerative efficiency up to 90%, it significantly reduces operating cost and cooling infrastructure compared with conventional load systems. Fast command response, sub-millisecond output dynamics, and advanced measurement accuracy ensure superior performance for high-speed power cycling, battery emulation, and converter testing.

Flexible connectivity—LAN (LXI Core), USB, and GPIB—supports seamless integration into automated test systems, while optional PathWave BenchVue Advanced Battery Test and Emulation software enables sophisticated battery simulation and high-capacity energy system validation.

Ideal applications include battery pack testing, DC-DC converter development, EV power module qualification, aerospace power subsystem verification, and renewable power conditioning research. For users requiring scalable and efficient high-power test architecture, the Keysight RP7942A presents a reliable and efficient solution.
