The Yokogawa PW482 Power Supply Module is engineered to provide stable and reliable power to critical components in Yokogawa distributed control systems. Designed for use within CENTUM VP and related automation architectures, the module converts incoming AC power into regulated internal supply voltages that support processors, communication modules, and I/O units.
In modern process plants where continuous operation is essential, power stability directly affects system reliability. The PW482 ensures uninterrupted energy delivery to control cabinets, helping prevent unexpected shutdowns and maintaining the integrity of automation networks.
The module can be installed in Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units. For higher system availability, two PW482 modules can be installed in a redundant configuration so that operations continue even if one unit fails.
