HP / Agilent 6626A DC Power Supply, 7V/0.015A, 16V/0.2A

The HP/Agilent 6626A is a precision quad-output linear DC power supply engineered for system integration and benchtop test applications. Four isolated outputs deliver 25 W or 50 W per section with dual-range capability, enabling flexible voltage and current delivery across diverse electronic testing and development scenarios. The instrument provides 14-bit resolution programming and readback, GPIB control with SCPI command support, and extensive DUT protection. Fast active down-programming, precise V and I control, and configurable series/parallel output operation make the 6626A suitable for automated test systems and manual bench work alike.
