PW302 Yokogawa | 100-240V AC Redundant DCS Power Supply

Yokogawa PW302 CENTUM CS 3000 / VP Power Supply Module

The PW302 (Model: PW302) is a foundational power supply unit engineered for Yokogawa’s CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS). This module is responsible for converting universal AC input into a stable, regulated DC voltage to power the control processors, I/O modules, and internal bus communication interfaces within the Field Control Station (FCS).

In mission-critical industrial environments, power stability is paramount. The PW302 (Part Number: PW302) features an advanced circuit design that filters electrical noise and protects downstream sensitive electronics from voltage surges and short circuits. It is specifically designed to support 1:1 dual-redundant configurations. When two PW302 modules are installed in a redundant rack, they perform active load-sharing; if one unit fails, the other assumes the full load instantaneously without a dip in output voltage, ensuring the DCS remains operational without process interruption.
