Product Brief
The Yokogawa PW482-11 is a high-reliability, system-grade power supply module. It delivers regulated DC power directly to Centum series control nodes and backplane assemblies. Engineered specifically to replace legacy PW482 hardware, this updated module stabilizes incoming electrical fluctuations. It ensures continuous processor operation and steady I/O bus communication during load transitions. The unit features standard 220V to 240V AC input compatibility to match standard industrial grid infrastructures. This rugged component provides the vital electrical backbone needed to prevent unexpected processor resets in critical automation systems.

Frequently Asked Questions
How does the PW482-11 replace the older PW482 model in terms of fit?
The PW482-11 features the exact physical footprint and exclusive connector interface of the older module. You can slide it directly into the existing backplane slot without modifying wiring.
What is the primary cause of premature power module failure on the factory floor?
Excessive heat buildup within unventilated cabinets is the leading cause of power supply degradation. Ensure your enclosure maintains positive ventilation to maximize the service life of your new hardware.
Can I hot-swap this power module while the Field Control Station is running?
If your system utilizes dual-redundant power module configurations, you can safely replace one unit while the station is active. For single-power systems, you must schedule a controlled system shutdown before extraction.
How do I verify if my input utility power is suitable for this specific module?
Measure the AC voltage at the backplane terminals; it must remain between 198V and 264V AC. Line frequency must stay within 47 Hz to 63 Hz to ensure continuous power conversion.
What parameters should I prioritize when ordering a spare Yokogawa power module?
Match your existing unit’s input voltage type (AC vs. DC) and model suffix codes exactly. For order assistance, connect with info@oiltechcontrols.com or WhatsApp at +86 158 8020 0923.
Procurement Guidance
- Verify if your cabinet backplane uses redundant power configurations prior to module installation.
- Check existing module suffix codes to ensure input voltage matches your local utility power grid.
- Purchase dual units to keep a hot-standby spare module inside your local maintenance warehouse.
- Ensure the system grounding terminals meet Yokogawa requirements to prevent electrical noise interference.
