1. At-A-Glance Executive Brief
- Model: 5466-1001
- Brand: Woodward
- Part Type: MicroNet-Plus Digital Controller Power Supply Module
- Lifecycle Status: Active / Supported System Line
- Input Voltage: 110 VAC / 125 VDC universal AC/DC range
- Output Rating: 24 VDC, 16 A
- Core Application: Providing isolated, high-reliability regulated power to CPU, I/O, and communication boards within Woodward MicroNet and MicroNet-Plus turbine control racks
2. Technical Introduction
A sudden power supply fault or internal rail voltage collapse in a critical turbine control rack can trigger unexpected emergency shutdowns, drop out fuel valves, and cause massive economic losses in power generation and oil and gas operations.
The Woodward 5466-1001 is a high-reliability digital controller power supply module engineered specifically for Woodward MicroNet-Plus industrial control platforms. Designed to accept a universal 110 VAC / 125 VDC input, it converts plant control power into stable, isolated low-voltage DC rails required by the rack’s processor, input/output cards, and communication modules. Supporting hot-redundant parallel configurations with built-in automatic current sharing, it guarantees uninterrupted operations for mission-critical prime movers. Deploying a verified original replacement module restores system power integrity without requiring chassis modifications.
Engineer’s Takeaway: Procuring an authentic Woodward 5466-1001 module ensures exact backplane pinout compatibility, precise voltage regulation limits, and full compliance with safety and marine certifications (CSA, ATEX, ABS, DNV), preventing critical path delays during emergency overhauls.

4. Field Engineer’s Tech Notes
- Input Power Isolation and Fusing: Always verify that upstream cabinet circuit breakers are locked out and tagged before inserting or extracting the power supply module from the MicroNet chassis. Although hot-swappable in redundant dual-supply architectures, care must be taken with live high-voltage 110VAC/125VDC terminal connections.
- Redundant Current-Sharing Verification: When replacing one unit in a dual-redundant power rack, check via the Woodward Control Explorer service software that the load current is evenly balanced between the primary and backup modules. An unbalanced load indicates an improper backplane seating or a failing companion module.
5. Adaptive QA & Testing Protocol
Every unit undergoes rigorous bench validation prior to dispatch. For the Woodward 5466-1001, our technicians mount the module in a dedicated MicroNet test rack simulator to verify 110VAC/125VDC input conversion, test stability across the 24VDC/16A output rails under dynamic loads, validate internal thermal protection cutoffs, and check front-panel diagnostic LED logic states (OK and Input Fault). Functional test reports or pre-shipment video verification can be provided upon request.
6. Buyer’s FAQ
- Are these power supply modules supplied as New Surplus or refurbished?
We stock both factory-sealed New Surplus (NSFP) and fully bench-tested, static-safe operational units. Condition status is explicitly marked on every quote.
- What warranty coverage comes with this part?
All replacement Woodward control modules are backed by a standard 12-month operational warranty from the date of invoice.
- How fast can this module ship to minimize turbine downtime?
In-stock items ship same-day via priority air courier services to global destinations, mitigating critical path delays during emergency power plant outage windows.
- Is the 5466-1001 interchangeable with the 5466-1000 module?
No. While both belong to the MicroNet power supply series, the 5466-1000 is designed for a 24VDC input source, whereas the 5466-1001 requires a 110VAC / 125VDC input supply. Verify your cabinet control voltage before ordering.
