The HP/Agilent 6274B is a regulated DC power supply delivering 0–60 V and 0–15 A in a full-rack format, engineered for precision testing, research, and industrial applications. It operates in dual modes—constant voltage (CV) and constant current (CC)—with line and load regulation tighter than 0.01% + 200 µV in CV mode. The 900 W supply includes analog metering, remote sensing, analog programming, and optional HP-IB, RS-232, and SCPI interfaces for automated control.
