Yokogawa PW482-50 Part # PW482-50 | Redundant PSU Module

Yokogawa PW482-50 Style S2 CENTUM VP Power Supply Module

The PW482-50 (Model: PW482-50) is a high-availability power supply module specifically engineered for the Yokogawa CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This module serves as a critical electrical regulator for the Field Control Station (FCS), converting AC input into the stabilized DC power necessary to drive control processors, I/O modules, and internal communication bus architectures.

As an S2 hardware style revision, this module represents an optimized design over legacy versions, offering improved thermal resilience and component longevity. The PW482-50 (Part Number: PW482-50) is particularly valued for its wide temperature operational capacity, supporting stable performance in environments ranging from -20°C to 70°C. To ensure mission-critical system uptime, it supports 1:1 dual-redundant configurations, allowing for a bumpless power failover that prevents process interruption or volatile memory loss in the event of a module failure.

Detailed Technical Specifications

The PW482-50 (Model: PW482-50) combines wide-range input flexibility with industrial-grade protection logic.
