Description
- The WOODWARD 5463-473 is a high-performance power supply module designed for use within the MicroNet TMR (Triple Modular Redundant) and MicroNet Simplex control systems. This module is engineered to provide stable, regulated power to the system’s control logic and I/O sections, ensuring seamless operation of critical prime mover applications such as gas or steam turbines. Built for industrial durability, it features advanced filtering and surge protection to withstand the electrical noise and fluctuations commonly found in power generation and heavy industrial environments.

This power supply is a critical backbone component, providing the necessary electrical isolation and voltage regulation required for the high-speed processing modules within the Woodward MicroNet architecture to function with maximum uptime.
Comparison with Similar Models
The 5463-473 is specifically optimized for Low Voltage DC inputs (24V nominal), distinguishing it from the 5464 series modules which are typically designed for High Voltage AC or DC inputs (e.g., 120/220V). Unlike standard industrial power supplies, the 5463-473 is purpose-built for the MicroNet “VME-style” backplane, allowing it to communicate status signals directly to the CPU. In a TMR configuration, this model works in synchronization with two other units to provide “two-out-of-three” voting logic, a feature not present in standard Simplex power modules.
Operation Tips
- Chassis Seating: Ensure the module is fully seated and the captive screws are tightened to the MicroNet chassis to maintain proper grounding and thermal contact.
- Redundancy Check: In TMR systems, periodically check the front-panel LEDs to ensure all power modules are active; a single failure will trigger a system alarm but will not shut down the turbine.
- Input Stability: While the module handles a wide DC range (18–36V), maintaining a steady 24V source will extend the lifespan of the internal capacitors and reduce heat generation.
- Hot Swapping: Before removing the module during live operation, verify that the redundant power supply is healthy and capable of carrying the full system load to avoid accidental shutdowns.
