Keysight (Agilent) N6743B DC Power Supply, 20 V, 5 A, 100 W, Programmable

The Keysight N6743B is a 100 W programmable DC power module engineered for integration into the N6700 Low-Profile Modular Power System or N6705 DC Power Analyzer. This single-slot module delivers 0–20 V and 0–5 A output with programmable voltage and current control, measurement capability, and comprehensive protection. It addresses cost-sensitive applications requiring basic power delivery and monitoring for device-under-test (DUT) excitation or ATE system resource power.
