Model: 5466-318
Brand: Woodward
Series: MicroNet Digital Control / MicroNet TMR
Core Function: Triple Modular Redundant (TMR) Kernel Power Supply module. Receives 24 VDC from the main MicroNet power supplies and regulates it to a precise 5 VDC output (up to 10 A) to power the kernel CPU and related sections in high-reliability turbine control systems.
HS Code: 8504.40 / 8537.10 (Static converters / Boards and panels for electric control)

Selection Suggestions and Precautions
Selection Suggestions:
- Confirm the system is a MicroNet TMR configuration.
- This module must be paired with a compatible TMR040 CPU module.
- Install only in the designated first (leftmost) kernel slot.
- Verify input power quality (24 VDC ±10%) from the main MicroNet supplies.
- Check for matching firmware/hardware revision if replacing an existing unit.
Precautions:
- Always de-energize the chassis before insertion or removal.
- Incorrect slot placement or missing TMR040 CPU will prevent proper operation.
- Follow Woodward MicroNet installation and power sequencing guidelines.
- Use only genuine Woodward batteries and accessories where applicable.
- Handle with ESD precautions.
- This is a critical power component — failure or improper installation can affect system availability.
