Description
Product Overview
The Woodward 5466-1001 is a power supply module for the MicroNet-Plus control platform. It occupies two chassis slots and provides power for compatible controller and I/O electronics used in demanding machine-control applications, including gas turbines, steam turbines, and compressors. Its role is power distribution rather than process-signal acquisition or execution of the control application itself.
The most important selection parameter is the input supply. The 5466-1001 is specified for the 110 VAC / 125 VDC input class, with published input ranges of 88–132 VAC at 50/60 Hz or 100–150 VDC. A physically similar module with a different input rating is not automatically suitable. Woodward identifies the 5466-1000 as the 24 VDC-input alternative and the 5466-1002 as the 220 VAC / 250 VDC-input alternative. Those variants should be treated as different supply configurations, not direct substitutes without an approved system-level change.
For maintenance and procurement teams, also check chassis compatibility, redundancy arrangement, and the health indicators on the module. Published product information describes current-sharing circuitry for redundant supplies and front-panel LEDs for normal operation, input faults, overtemperature, and power-supply faults. Output-current specifications vary across secondary listings, so the correct output ratings should be taken from the applicable Woodward manual and system configuration rather than assumed from a reseller description.
Woodward issued a product-change notice in March 2025 stating that new orders for the 5466-1001 were temporarily affected by component-supply restrictions, with resolution then anticipated by Q1 2026. That notice does not establish the current October 2026 ordering status; confirm availability and any approved replacement guidance with Woodward before planning a system conversion.
Product Introduction
The Woodward 5466-1001 MicroNet-Plus power supply is designed for compatible control chassis that require a 110 VAC / 125 VDC input supply. It supports the power architecture of control systems used in turbomachinery and other industrial applications.
Before replacing a module, verify the complete part number, input supply, chassis configuration, and redundancy design. After installation, check the module status indicators and confirm that the controller and I/O hardware report normal power status. Follow the applicable shutdown, isolation, and commissioning procedures.

Frequently Asked Questions
Q1: What is the Woodward 5466-1001 used for?
It supplies power to compatible MicroNet-Plus controller and I/O chassis electronics in industrial control applications, including turbomachinery systems.
Q2: What input voltage does it require?
The specified input class is 110 VAC or 125 VDC. Published ranges are 88–132 VAC at 50/60 Hz and 100–150 VDC. Confirm the installed supply and nameplate before connecting power.
Q3: Can the 5466-1000 or 5466-1002 replace it?
Not automatically. The 5466-1000 uses a 24 VDC input class, while the 5466-1002 is for the 220 VAC / 250 VDC class. Use an alternative only after confirming the approved configuration and available input supply.
Q4: Does the module support redundant operation?
Published descriptions identify current-sharing circuitry and use in supported redundant power arrangements. Confirm the chassis wiring and redundancy design in the applicable Woodward manual before removing a supply during operation.
Q5: Can the module be hot-swapped?
Some product descriptions report replacement capability in supported redundant configurations, but this should not be generalized to every installation. Follow the exact manual and site procedure; do not remove the module under power unless the installed configuration explicitly permits it.
Q6: What should be checked when a power-supply fault appears?
Check the input supply, chassis connections, status LEDs, and related power-distribution components according to the troubleshooting procedure. Do not repeatedly reset or replace the module without establishing whether the fault originates in the input source, the supply, or the downstream load.
Q7: What should a buyer request for a used or refurbished unit?
Request clear photographs of the nameplate, confirmation of the 5466-1001 part number, condition details, and a functional test report. For a critical controller, also verify current product status and approved replacement guidance with Woodward before committing to a substitute.
