Yokogawa PW482-10 S2 – Redundant Power Supply Module | CENTUM VP DCS Platform
Engineering Background
The PW482-10 S2 is a field-proven power supply module engineered for Yokogawa’s CENTUM VP distributed control system. Designed to deliver stable, regulated DC power to I/O and controller nodes in continuous-process environments, it supports hot-standby redundancy configurations that eliminate single points of failure in mission-critical plant infrastructure.
Product Positioning
Targeted at process automation engineers and MRO procurement teams in oil & gas, petrochemical, power generation, and pharmaceutical industries, the PW482-10 S2 is the preferred replacement and spare-parts choice for CENTUM VP cabinets requiring IEC-compliant, OEM-grade power integrity.

System Architecture & Signal Flow
In a CENTUM VP cabinet, the PW482-10 S2 receives AC mains input (via upstream power conditioning) and converts it to regulated DC bus voltage distributed to the field control station (FCS) backplane. In redundant configurations, two PW482-10 S2 modules operate in parallel; upon primary module fault detection, the standby unit assumes full load within milliseconds — transparent to the control loop. The module communicates power-status diagnostics to the CENTUM VP system bus, enabling predictive maintenance alerts via the HIS engineering station.

Technical FAQ
Q: Is the PW482-10 S2 compatible with all CENTUM VP revisions?
A: The module is designed for the CENTUM VP platform. Confirm hardware revision compatibility with your system’s BOM or contact our technical team for cross-reference support.
Q: Can this module be used in a non-redundant single-power configuration?
A: Yes. The PW482-10 S2 operates in both simplex and redundant configurations. Redundancy requires a second module and appropriate backplane support.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock inquiries, contact us for sourcing lead time.
Q: Do you provide a warranty?
A: Yes. All modules carry a 90-day functional warranty. Extended warranty options available upon request.
Q: Can you provide an OEM datasheet?
A: Official Yokogawa datasheets and manuals are available upon request. Contact [email protected].
