Product Overview

The PW482-S01 is a high-stability power supply module within the Yokogawa CENTUM VP platform, designed to deliver regulated DC power to Field Control Units (FCU). It forms the electrical foundation of the DCS hardware by converting incoming AC mains power into clean, low-noise DC suitable for processor and communication modules.

Engineered with industrial-grade filtering and protection, the PW482-S01 safeguards sensitive control electronics from line noise, voltage spikes, and transient disturbances. Manufactured in the USA, it meets strict quality and reliability standards for continuous operation in critical infrastructure such as refineries, petrochemical plants, and power generation facilities.

Technical Specifications

Key Operational Benefits

• Redundancy-Ready: Supports parallel operation with an identical unit to maintain power during module failure

• Stable Output: Maintains regulated DC levels during transient load changes from CPUs and I/O polling

• Clear Diagnostics: Front-panel LED indicators provide instant AC input and DC output status

• Compact Design: Optimized for dense cabinet layouts and standardized power nests

FAQ

What differentiates the PW482-S01 from standard PW482 variants?
The S01 suffix denotes a specific variant that may incorporate region-specific component selection or configuration to match particular power nests or system requirements within the CENTUM ecosystem.

Can a PW482-S01 replace a PW482-10?
Not always. While they share the same PW482 family, connector type, current rating, and redundancy logic must match. It is best practice to replace power supplies with the exact same suffix to ensure full mechanical and electrical compatibility.
