Engineering Advantages

Redundancy for Zero Downtime: The NFPW426-50 supports parallel redundant configurations. Installing two modules in a redundant pair ensures that the control system continues to operate without interruption if one module encounters a fault or requires maintenance.
Fanless Reliability: The module utilizes natural convection cooling. By removing mechanical fans—a common point of failure—Yokogawa drastically increases the MTBF (Mean Time Between Failures) and eliminates maintenance requirements related to fan dust accumulation.
Advanced Fault Protection: Integrated over-voltage, over-current, and short-circuit protection circuits immediately isolate electrical anomalies. This safeguards expensive downstream CPU and I/O hardware from damage during external power surges or field-side wiring faults.
Space-Efficient Design: The compact width (under 50mm) facilitates high-density deployments. This allows engineers to install more I/O points within smaller control cabinets, reducing the overall footprint of the STARDOM FCN-RTU system in remote or offshore locations.
Hot-Swap Functionality: Depending on the rack configuration, the NFPW426-50 permits hot-swapping. Technicians can replace a power module while the system remains live, eliminating the need for process shutdowns during routine power system upgrades.

FAQs

Can I mount the NFPW426-50 on any Yokogawa rack?No. Technical requirements mandate that this module mounts only on the NFBU050 base module. Verify your rack model number before installation to ensure mechanical and electrical compatibility.
Does this module support explosion-proof environments?The "-5" suffix indicates this is the standard type with no explosion protection. For hazardous locations requiring specific certifications (ATEX, IECEx), please contact us for the appropriate explosion-protected variant.
What is the benefit of the 50W rating for FCN-RTU systems?The 50W output provides ample overhead for a fully loaded FCN-RTU rack, including high-consumption communication modules and analog I/O, ensuring voltage stability even during peak demand.
Why is "Brand New" condition critical for NFPW modules?Power modules contain electrolytic capacitors that age and lose effectiveness over time, especially in used or "New Old Stock" units. A 100% Brand New NFPW426-50 guarantees factory-fresh capacitors, providing the full 85% efficiency and the stable ripple-free DC power essential for high-speed CPU logic.
