Keysight RP5945A Regenerative DC Power Supply

Overview

The Keysight RP5945A is a compact regenerative DC power supply with integrated electronic load capability designed for high-power testing in laboratory and production environments. The unit combines a bidirectional source and electronic load in one platform, efficiently returning absorbed energy to the grid (up to 95% recovery) to reduce energy costs and cooling requirements. With built-in voltage and current measurement capabilities, LAN/USB/CAN connectivity, and web-based remote control, it accelerates test development for battery emulation, power transient testing, and high-power device validation.

Key Features
