Keysight (Agilent) N6731B DC Power Supply, 5 V, 10 A, 50 W, Programmable

The Keysight N6731B is a 50 W programmable DC power module engineered for the N6700 Low-Profile Modular Power System and N6705 DC Power Analyzer. This single-output, 1U high form factor module delivers 5 V at up to 10 A with integrated measurement and protection capabilities. Designed for automated test equipment systems, it powers devices under test and ATE resources such as fixture control in R&D, design validation, and manufacturing test environments.

The compact slot design permits up to four modules in a single rack space, enabling flexible system scaling across multiple voltage and current levels.
