Product Overview
The Woodward 5466-318 is a MicroNet TMR Kernel Power Supply (PS) Module engineered for triple modular redundant (TMR) control platforms. Developed by Woodward in the United States, this specialized power module receives a 24 Vdc input (±10%) from the main chassis power supply and converts it into a highly regulated 5 Vdc output (±5%) delivering up to 10 A max. Dedicated to powering the core kernel section of each sub-chassis, the 5466-318 provides the necessary voltage for critical CPU and system modules while generating a 5 Vdc precharge voltage to ensure safe, surge-free startup sequences. Weighing approximately 1.20 kg (2.65 lbs), the module includes a front-panel health status LED and plays a vital role in maintaining the high-availability architecture of mission-critical control applications.

Key Hardware & Operational Features
- Fault-Tolerant TMR Architecture: Dedicated kernel power supply per section ensures that a failure in one kernel path will not interrupt adjacent running channels.
- Integrated Precharge Circuitry: Produces a controlled 5 Vdc precharge voltage to prevent inrush current surges during hot-swapping or initial sub-chassis energization.
- High Current Output Capacity: Supplies up to 10 Amps of clean, regulated 5 Vdc power to drive kernel-level processors and processing logic.
- Real-Time LED Diagnostics: Features a dedicated LED indicator providing instant status verification of the power supply's output state.
Installation & Module Placement Guidelines
1. Dedicated Slot Placement: For each MicroNet sub-chassis (kernel), install the 5466-318 Kernel Power Supply module into the first slot from the far left.
2. Adjacent CPU Installation: Install the Kernel CPU module into the slot immediately to the right of the 5466-318 module to maintain proper backplane power distribution.
3. Securing Hardware: Insert the module firmly into the chassis backplane connectors and tighten top/bottom retaining screws to complete grounding.
