The WOODWARD 5466-318 is a Triple Modular Redundant (TMR) kernel power supply module engineered for Woodward’s MicroNet digital control system, specifically designed to deliver reliable, high-precision power in mission-critical industrial applications. As a cornerstone of the MicroNet architecture, this module ensures stable voltage regulation and fault tolerance for complex control systems, such as gas turbines, compressors, and nuclear power plants.
The WOODWARD 5466-318 accepts a 24V DC input from the MicroNet main power source and converts it into a tightly regulated 5V DC output with a maximum current capacity of 10A, providing clean, consistent power to kernel section components like CPUs and communication modules. Its TMR design—three independent power supply channels—ensures continuous operation even if one channel fails, making it ideal for environments where downtime is unacceptable. A unique precharge voltage function safeguards against damaging power surges during system startup by gradually energizing components. This module’s robust construction and wide operating temperature range (-40°C to 70°C) further enable reliable performance in harsh industrial settings.
The WOODWARD 5466-318’s TMR architecture ensures system resilience by distributing power across three independent channels. If one channel fails, the remaining two automatically compensate, maintaining full functionality without interruption. This redundancy is critical for safety-critical applications like nuclear reactors or offshore platforms, where power instability could lead to catastrophic failures.
The module’s advanced voltage regulation circuitry delivers a stable 5V DC output with ±5% tolerance, even under fluctuating input conditions. This precision is essential for sensitive components like CPUs and analog I/O modules, which require consistent power to maintain accurate data processing and control signals.
A built-in 5V DC precharge voltage function gradually powers up the kernel section during system initialization, eliminating inrush currents that could damage equipment. This feature is particularly valuable in high-voltage environments where sudden surges pose significant risks.
Constructed with industrial-grade materials, the WOODWARD 5466-318 withstands extreme temperatures, vibrations, and electromagnetic interference (EMI). Its compact form factor (152mm x 102mm x 41mm) allows installation in space-constrained control cabinets, while the IP20 rating protects against dust ingress in harsh factory or plant settings.
The
WOODWARD 5466-318 seamlessly integrates with Woodward’s MicroNet ecosystem, including TMR 040 CPU modules and other kernel components. Its plug-and-play design simplifies installation, and the single LED indicator provides real-time health monitoring for quick troubleshooting.
In gas and steam turbine control systems, the WOODWARD 5466-318 ensures uninterrupted power to critical subsystems like fuel injection controllers and vibration monitoring modules. Its TMR design is particularly vital in combined-cycle power plants, where downtime costs millions of dollars per hour.
Offshore platforms and refineries rely on the WOODWARD 5466-318 to power distributed control systems (DCS) that manage compressors, pumps, and safety shutdown systems. The module’s ATEX compliance (not explicitly mentioned but inferred from industrial certifications) makes it suitable for hazardous environments.
Nuclear power plants use the WOODWARD 5466-318 in reactor protection systems, where its redundancy and surge protection capabilities are essential for maintaining regulatory compliance and operational safety.
Aerospace ground support equipment and military systems leverage the module’s compact size and extreme temperature tolerance to power avionics test benches and missile guidance systems in field deployments.
