The Keysight N8950A is a 10 kW autoranging system DC power supply engineered for automated test equipment (ATE) applications requiring precise, flexible power delivery. This single-output unit delivers 0–1000 V, 0–30 A, and up to 10,000 W within a compact 3U rack form factor. Unlike fixed-output supplies, the N8950A’s autoranging architecture dynamically adjusts voltage and current combinations across its full power envelope, eliminating the need to over-specify equipment for varying load conditions.
