HP / Agilent 66105A DC Power Module, 120V, 1.25A

The HP/Agilent 66105A is a 150 W DC power module engineered for integration into automated test equipment and production test systems. This programmable supply delivers 0–120 V at 0–1.25 A with exceptional stability and control. It features over-voltage and over-current protection, electronic calibration, self-testing, and five nonvolatile store-recall states per output. The 66105A is a member of the Agilent 66000 Modular Power System, which supports high-density configurations of up to eight 150 W modules in a single 4U mainframe, reducing rack footprint and simplifying interconnect complexity.
