The Keysight (formerly Agilent) N6740 Series consists of basic DC power modules providing 100 W of programmable voltage and current for the N6700 Low-Profile Modular Power System and N6705 DC Power Analyzer mainframes. Designed for economy and flexibility, the series includes the N6741B, N6742B, N6743B, N6744B, N6745B, and N6746B modules, covering voltage ranges up to 100 V and currents up to 20 A. These 1-slot modules are ideal for providing power to devices under test (DUT) or automating ATE system resources.
