Product Introduction
When a power supply failure threatens critical processes, the Woodward 5466-318 MicroNet TMR Kernel PS Module ensures uninterrupted operation. This module receives 24 Vdc from the main MicroNet power supplies and regulates it to a stable 5 Vdc output, delivering up to 10 A to power kernel components. Its design supports safe startup sequences through a precharge voltage mechanism, protecting the system from surges. As part of the MicroNet TMR family, this module is built for high-availability applications.

The Woodward 5466-318 provides precise voltage regulation with ±5% tolerance on the 5 Vdc output, ensuring stable power to sensitive kernel modules. Its 10 A current capacity meets the demands of multiple critical components in the kernel section.
Application Scenarios
The Woodward 5466-318 excels in safety-critical industries such as nuclear power plants, aerospace systems, and other mission-critical environments where fault tolerance is paramount. In a triple-modular redundant (TMR) architecture, this module powers the kernel section independently. If one power supply fails, the remaining kernels continue operation, preventing downtime. This module is also suitable for any industrial automation setup requiring a dedicated 5 Vdc power source with high current capacity.
Installation & Setup Guidance
For each sub-chassis (kernel), install the Woodward 5466-318 in the first module slot from the left. After securing the module, place the Kernel CPU module in the immediately adjacent slot to the right. This sequential placement ensures correct configuration and seamless communication. Ensure the input voltage is within 24 Vdc ±10% before connecting. No additional calibration is required.
Maintenance & Reliability
The Woodward 5466-318 includes a single LED that indicates the health of the power supply. Regularly check this LED during routine inspections. The module's design isolates each kernel's power supply, so a failure in one does not affect others. This architecture reduces overall system downtime and maintenance costs. For optimal lifespan, operate within rated voltage and current limits.
Selection Guide & Purchasing Advice
When selecting the Woodward 5466-318, verify compatibility with your MicroNet TMR system's kernel configuration. Ensure your power source delivers 24 Vdc ±10%.
