The Keysight/Agilent/HP 66106A is a 150 W DC power module engineered for automated test equipment and production testing. This modular supply delivers 0–200 Vdc at 0–0.75 A and integrates into the 66000A Power System Mainframe, allowing up to eight modules in 4U rack space. The architecture prioritizes output density and operational flexibility in space-constrained test environments.
