YOKOGAWA PW482-51 S2 Redundant Power Supply Module – CENTUM VP / CS 3000 Series
When a power supply module fails in a live DCS environment, the consequences are immediate and severe: process shutdowns, unplanned downtime, safety system trips, and potentially millions of dollars in lost production. In critical industries such as oil & gas, petrochemicals, and power generation, even a momentary interruption to the control system power rail can cascade into plant-wide emergencies. The YOKOGAWA PW482-51 S2 is engineered precisely to eliminate this risk — delivering stable, redundant DC power to field control stations (FCS) within the CENTUM VP and CS 3000 distributed control systems.
The PW482-51 S2 occupies a well-established position within YOKOGAWA’s CENTUM VP power supply lineup. As a hot-standby redundant module, it operates in parallel with a primary power unit, automatically taking over load without interruption upon primary failure. This model is widely deployed across refineries, LNG terminals, chemical plants, and utility facilities globally — making it one of the most field-proven DCS power modules in the industrial automation market.
