Product Overview

The Yokogawa PW482-50 S2 serves as a high-reliability power conversion unit for the CENTUM CS3000 and CENTUM VP Distributed Control Systems (DCS). Specifically optimized for 220–240V AC environments, it provides regulated 24VDC power to process controllers, I/O modules, and critical field interfaces. We supply this unit as 100% Brand New and Original, featuring the S2 revision for updated safety compliance and superior thermal resilience in extreme industrial climates.

Part Number Breakdown: PW482-50

Technical Specifications

Engineering Advantages

• Extreme Climate Resilience: Unlike standard power modules limited to 50°C, the PW482-50 operates flawlessly from -20°C to +70°C. This capability allows for installation in remote marshaling cabinets and outdoor shelters without requiring expensive HVAC overhead.

• Active Load-Sharing Redundancy: Two PW482-50 S2 modules integrate seamlessly within a single CENTUM rack to provide a fault-tolerant power bus. If one unit fails, the redundant partner assumes the full electrical load instantly, preventing controller downtime and data loss.

• Revision S2 Hardware Architecture: The S2 revision incorporates modernized internal components that improve surge suppression and thermal efficiency. This update specifically targets the elimination of common-mode noise that can interfere with sensitive analog signal processing.

• Hot-Swappable Functionality: Maintenance engineers can replace a faulty module while the system remains live. The design ensures that extracting or inserting a module does not cause voltage dips on the backplane, maintaining 100% plant availability.

FAQs

Q: Can I use the PW482-50 S2 in a 110V AC system?

A: No. The PW482-50 is specifically engineered for 220–240V AC inputs. For 110V AC environments, you must select the PW482-10 or PW401 series to match your site's electrical infrastructure.

Q: Does this module require manual configuration for redundant operation?

A: No. When you seat two PW482-50 S2 modules into the same power rack, they automatically perform load sharing. The DCS backplane monitors the health of both units and generates an alarm if either unit deviates from safe operating parameters.

Q: Is this "S2" version backward compatible with my older "S1" racks?

A: Yes. The PW482-50 S2 serves as a direct drop-in replacement for legacy PW482 versions. It maintains the same physical form factor and electrical pinout while offering updated internal reliability standards.

Do you need a single replacement unit or a full redundant pair to ensure zero-downtime operation?
