Product Overview

The ABB NPOW-02, part number 3535000901, is a high-reliability power driver module engineered for the Advant OCS and 800xA control platforms. This board functions as a specialized redundant power interface, ensuring that critical control logic and driver circuits receive uninterrupted, stabilized voltage. Designed for high-availability environments, the NPOW-02 manages the transition between power sources and provides essential isolation between the primary supply and the sensitive electronics of the Distributed Control System (DCS). Its architecture supports hot-swapping, allowing for live system maintenance without risking a process shutdown, which is vital for continuous industrial operations.
