Keysight (Agilent) N8926A Autoranging System DC Power Supply, 200 V, 140 A, 10000 W

The Keysight N8926A is a 10 kW autoranging DC power supply engineered for automated test equipment and high-power load applications. Its autoranging output delivers flexible voltage and current combinations at full power, eliminating the need for multiple fixed-range supplies. The unit operates from three-phase AC input (187–240 VAC, 45–65 Hz) and fits within a compact 3U rack form factor, making it suitable for space-constrained test benches and production environments.
