Product Overview

The PW482-50 S2 is a mission-critical power supply module designed for the Yokogawa CENTUM VP Distributed Control System (DCS). It provides stable, regulated DC power to Field Control Unit (FCU) components, ensuring reliable processor operation and accurate I/O signal processing.

Engineered for harsh industrial environments, the PW482-50 S2 incorporates advanced noise filtering and surge suppression to protect sensitive control electronics. As a Style S2 revision, it features an enhanced hardware design optimized for improved thermal stability and long-term reliability in 24/7 continuous process operations.

Technical Specifications

System Integration & Reliability

• Redundant Operation: In duplex configurations, two PW482-50 S2 units share the load; if one fails, the remaining unit instantly assumes full load without system reset

• Diagnostic Visibility: Front-panel LED indicators provide clear Power OK and Fault status at a glance

• Electrical Protection: Integrated filtering and surge protection safeguard CPUs and I/O modules from electrical disturbances

• Industrial Durability: Manufactured to strict industrial quality standards for long-term cabinet operation

FAQ

What does the “-50” designation indicate?
The -50 suffix typically refers to a specific input voltage/frequency configuration compatible with standard 50/60 Hz industrial power grids, supporting global deployment.

Should redundant power supplies use the same Style Code?
Yes. For proper load sharing, mechanical fit, and thermal behavior, it is strongly recommended to use identical modules (e.g., two PW482-50 S2 units) in redundant power configurations.
