Product Overview

The SPW481-53 (Model: SPW481-53) is a ruggedized system power supply module engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Specifically optimized for 100-120V AC input infrastructures, this module provides highly regulated DC power to drive critical Field Control Station (FCS) components, including control processors, I/O modules, and communication interfaces.

As a premium hardware revision, the SPW481-53 (Style S1) is built to ISA Standard G3 specifications. This includes a specialized conformal coating that protects internal circuitry from corrosive gases (such as H2S and SO2) typically found in heavy industrial environments. Furthermore, it features an extended operating temperature range of -20°C to +70°C, ensuring reliability in non-climate-controlled remote instrument enclosures. To guarantee mission-critical uptime, the SPW481-53 supports 1:1 dual-redundant configurations, providing a bumpless power failover in the event of a module or source failure.

Technical Specifications

The SPW481-53 combines extreme environmental resilience with high-precision electrical regulation.
