The Yokogawa PW482-10 Power Supply Module is a high-reliability AC input power unit designed for use within Yokogawa distributed control architectures such as CENTUM CS and CENTUM VP. It converts incoming AC power into stable internal DC voltages required by CPUs, communication modules, and I/O subsystems inside the control rack.
Industrial control systems require consistent and uninterrupted power delivery to ensure safe and stable plant operation. The PW482-10 module is engineered with industrial-grade components and protection mechanisms that help maintain system uptime even in demanding environments such as oil & gas plants, chemical processing facilities, and power generation stations.
This module can be installed in Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units. For critical applications, two modules can be installed in a redundant configuration to provide continuous power even if one unit fails.
