Agilent / Keysight N6701A Low-Profile Modular Power System Mainframe, 600W, 4 Slots

The Keysight N6701A is a 1U-high, 4-slot modular power system mainframe delivering 600 W total output capacity for automated test and benchtop applications. This low-profile mainframe accepts up to four N6700 series DC power modules - ordered separately - and supports N678x SMUs and N679x electronic loads. LXI Class-C compliant with GPIB, LAN, and USB interfaces, it enables flexible remote control via integrated web server and SCPI command set.

System integrators can choose from over 30 compatible modules (20 W to 300 W each) to build optimized solutions for performance, precision, and cost.
