Keysight (Agilent) N8948A Autoranging System DC Power Supply, 500 V, 60 A, 10000 W, 400 VAC

The Keysight N8948A is a high-power autoranging DC power supply engineered for automated test equipment and demanding applications requiring precise, flexible power delivery. Unlike fixed-output supplies, this unit dynamically adjusts voltage and current combinations across its full 10,000 W power envelope, enabling efficient operation across diverse test scenarios. Operating from 360–440 VAC (400 VAC nominal) input, the N8948A integrates into the N8900 Series platform and supports parallel operation to exceed 100 kW total output.
