Product Overview

The PW482-11 (Model: PW482-11) is a high-availability power supply unit engineered for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This module serves as a primary power source within the Field Control Station (FCS), converting universal AC input into stable, regulated 24V DC power required to drive control processors, I/O modules, and system communication interfaces.

As an advanced hardware iteration, the PW482-11 (Part Number: PW482-11) features improved component longevity and optimized thermal management compared to the legacy PW482-10. It is designed for mission-critical availability, supporting 1:1 dual-redundant configurations. In a redundant setup, if one PW482-11 fails or loses input power, the partner module assumes the full load instantaneously with a "bumpless" transition, ensuring no disruption to real-time process control or data integrity.
