6540 Series - 200W

Keysight Technologies (Agilent HP)Agilent HP

The Keysight (Agilent/HP) 6540 Series comprises 200W, single-output DC system power supplies designed for general-purpose applications on the bench or in analog-controlled systems. Unlike the related 6640 Series, the 6540 Series models (6541A through 6545A) do not include standard digital interfaces like GPIB, relying instead on front-panel and analog control. They offer fast up- and down-programming, remote sensing, and comprehensive overvoltage and overcurrent protection.
