Keysight (Agilent) N8941A Autoranging System DC Power Supply, 200 V, 70 A, 5000 W

The Keysight N8941A is a 5 kW autoranging DC power supply engineered for automated test equipment (ATE) systems requiring high power density and flexible output configurations. Delivering 0–200 V and 0–70 A at full 5000 W rating, it functions as multiple power supplies in a single 3U rack-mount unit. The autoranging topology eliminates the constraints of traditional rectangular output designs, enabling a wide range of voltage and current combinations at maximum power.

Built-in voltage and current measurement capabilities, combined with LAN (LXI Core), USB 2.0, GPIB, and analog interfaces, streamline integration into automated test systems. Multiple N8900 Series units parallel via integrated link to deliver over 100 kW aggregate power.
