Product Overview
The Woodward 5501-467 is a MicroNet Simplex power supply board designed for Woodward MicroNet digital control systems. It accepts a nominal 220 VAC/VDC input and provides the DC power required by the compatible MicroNet chassis and control electronics. Woodward documentation identifies this part as a MicroNet single power supply for 220 VAC/DC applications, with applicable certifications including CSA, CE, ABS, DNV, and LRS.
The board is intended for MicroNet Simplex and compatible MicroNet Plus chassis applications, but its operating configuration must be checked carefully before replacement. Available technical data specify an input range of 180–264 VAC at 47–63 Hz and a maximum 5 VDC output current of 22 A at 65°C.

Installation and Maintenance — 5501-467
Before replacement, isolate the incoming power and verify that the supply is completely de-energized. Record the chassis slot, input wiring, module condition, and associated system configuration before removing the board.
Inspect the board connector, extraction hardware, and chassis backplane for contamination or damage. After installation, verify the input voltage and confirm that the MicroNet system receives stable DC power. Check system diagnostics and connected control modules before returning the controller to service.
Personally, I would verify the actual incoming voltage before installing the spare. A 220 VAC/DC power board is not an interchangeable substitute for the lower-voltage MicroNet variants.
Product Warranty — 5501-467
Warranty coverage depends on the supplier, equipment condition, and purchase agreement. For new-old-stock, surplus, or refurbished inventory, confirm the exact part number, hardware revision, serial number, inspection status, functional-test results, and warranty period.
The Woodward 5501-467 should be managed as an exact MicroNet power-supply spare, with input voltage, chassis compatibility, and system configuration verified before installation. Woodward provides product-history lookup tools using the product label and part number for maintenance and lifecycle verification.
