Woodward 5466-318 Kernel Power Supply 5V 10A
Product Introduction
The Woodward 5466-318 serves as the primary electrical foundation for the kernel sections of a MicroNet TMR control system. Specifically, this module receives 24 Vdc ±10% from the main power supply and regulates it down to a precision 5 Vdc ±5% output. Furthermore, with a maximum current capacity of 10 A, it provides ample power for the high-speed CPU modules and internal logic required in mission-critical environments like aerospace or nuclear power plants.
Fault Tolerance and Redundancy
A key feature of the Woodward 5466-318 is its contribution to the system's overall fault tolerance. Because each kernel section has its own independent power supply, a failure in one section does not compromise the others. Consequently, the remaining kernel sections continue to operate without interruption, ensuring the safety of the controlled process. Meanwhile, a single Health LED on the front faceplate provides technicians with immediate visual confirmation of the module's operational status.
Integrated Precharge Logic
Beyond standard regulation, the Woodward 5466-318 plays a vital role in the system's startup safety. Specifically, it generates a 5 Vdc precharge voltage that facilitates controlled energization during the initial power-up phase. Therefore, this mechanism protects sensitive electronic components from potential inrush surges or voltage instabilities. By implementing this gradual power-on sequence, the module significantly extends the lifespan of the entire control sub-chassis.

Installation Guide
First, ensure the MicroNet TMR chassis is completely de-energized before attempting to insert the hardware. Next, identify the first slot from the left of the sub-chassis, as this is the mandatory location for the Woodward 5466-318. After that, slide the module firmly into the slot and tighten the mounting screws to ensure proper grounding. Finally, verify that the Kernel CPU module is installed in the slot immediately to the right, as this specific sequence is required for correct internal bus communication and power distribution.

FAQ
Q: Can I install the Woodward 5466-318 in any slot within the chassis?
A: No, it must be installed in the first slot on the far left of the sub-chassis to ensure proper power distribution.
Q: What is the purpose of the 5 Vdc precharge voltage?
A: Specifically, the precharge voltage ensures a safe and gradual energization of internal components, preventing damage from power surges during startup.
Q: Does a failure in this module shut down the entire TMR system?
A: No. Due to the modular architecture, the other kernel sections continue to run independently, maintaining overall system control and safety.
