Product Introduction
The ABB Bailey NPSM02 is a robust, industrial-grade power supply module designed to support the Bailey INFI 90 Distributed Control System (DCS). As a core component of ABB’s legacy control infrastructure, the NPSM02 delivers stable, regulated DC power to vital system modules, ensuring reliable operation in mission-critical process environments.
Built to meet the demands of continuous, high-performance operation, the NPSM02 excels in maintaining voltage regulation, electrical noise suppression, and protection against overcurrent or short-circuit conditions. It is engineered with high thermal efficiency, long operational life, and strong environmental resilience—making it ideal for industrial facilities that demand zero downtime.
The NPSM02 supports redundancy, enabling fail-safe operations when paired with a secondary unit in critical systems. It plays an essential role in maintaining operational integrity within refineries, power plants, paper mills, and other process-intensive industries.
