The Yokogawa Power Supply and Battery series encompasses high-reliability energy management solutions engineered specifically for the CENTUM VP, CENTUM CS 3000, and ProSafe-RS control architectures. These industrial-grade power modules provide stable DC voltage to system backplanes, CPU nests, and I/O racks, featuring advanced noise filtering and surge protection to ensure signal integrity in electromagnetic-heavy environments. Key hardware includes the PW481 and PW482 redundant power supply modules, which support hot-swappable configurations to prevent system downtime during maintenance. Complementing these are high-capacity battery units designed for volatile memory backup and real-time clock synchronization during primary power loss. Built to withstand extreme thermal fluctuations and vibration, Yokogawa’s power infrastructure is essential for maintaining the high-availability requirements of continuous process industries such as oil refining, petrochemicals, and power generation.
