Product Overview
The WOODWARD 5466-1049 is a MicroNet TMR Kernel Power Supply module designed for Woodward MicroNet and 5009FT turbine control systems. Its primary function is to accept a nominal 24 VDC system input and provide regulated power for the kernel section of the TMR controller. Woodward lists this module as a recommended spare for critical 5009FT applications and places it in the first slot of each A, B, and C kernel section. It is intended to work with the TMR5200 CPU architecture, making correct system matching important during replacement.
For maintenance teams, this is not simply a generic DC power converter. The module forms part of the controller’s redundant power architecture, so replacement should consider the complete kernel configuration, input supply quality, hardware revision, and installed CPU. Personally, I would verify the chassis slot and system documentation before installing a replacement, especially on an operating turbine.

Installation and Maintenance — 5466-1049
Before replacement, isolate the appropriate power source and follow the site’s turbine-control maintenance procedure. Confirm that the incoming DC supply is within the specified range, then inspect the module, connectors, chassis slot, and associated kernel wiring for damage or contamination.
Because the MicroNet TMR architecture uses three kernel sections, maintenance personnel should verify the correct redundant section before removal. After installation, check the health indication, confirm the expected 5 VDC output, review controller diagnostics, and verify normal TMR operation before returning the control system to service.
Product Warranty — 5466-1049
Warranty terms depend on the supplier and product condition, so the purchase record should clearly identify the exact part number, hardware revision, serial number where applicable, test status, and warranty period. For turbine-control spares, documented inspection and functional verification are recommended before warehouse release.
The WOODWARD 5466-1049 remains a directly relevant spare for existing MicroNet TMR and 5009FT installations where the specified 24 VDC kernel power architecture is required.
