Product Overview

The PW482-50 (Model: PW482-50) is a high-availability power supply unit (PSU) engineered for the Yokogawa CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This module serves as the primary electrical regulator for Field Control Stations (FCS), converting AC input into the stabilized DC power required to drive control processors, I/O modules, and internal communication bus architectures. The PW482-50 (Part Number: PW482-50) is a critical component for ensuring the continuous operation of mission-critical control hardware.

Utilizing the S2 hardware style revision, this module features an optimized internal design for enhanced thermal resilience and extended component life. To maintain maximum system uptime, the PW482-50 supports 1:1 dual-redundant configurations. In this setup, two modules operate in parallel; if one unit fails, the other assumes the full load instantaneously without any voltage drop or process interruption. This "bumpless" failover is essential for preventing volatile memory loss and maintaining control stability in high-stakes industrial environments.
