The Keysight Technologies (Agilent HP) 6227B is a classic, highly reliable dual-channel linear DC power supply. Designed for versatile benchtop and system applications, it provides dual independent outputs of 0 to 25 V and 0 to 2 A. For increased output flexibility, it supports auto-series, auto-parallel, and auto-tracking configurations, allowing both sections to act as a single coordinated supply.
