The HP/Agilent 6448B is a single-phase DC power supply delivering 0–600 V at 0–1.5 A, producing up to 900 W of regulated output power. Designed for laboratory test benches, research facilities, and production environments, this unit operates from 115 VAC ±10% input (57–63 Hz) and provides both constant voltage and constant current regulation modes with front and rear output terminals.
