WOODWARD 5461-655 Power Supply | Replacement, Equivalent & Selection Guide
The WOODWARD 5461-655 is an industrial-grade power supply module designed for use within WOODWARD control and governor systems. It provides stable, regulated DC power to downstream control modules, I/O cards, and communication interfaces in turbine, engine, and generator management applications. As a critical infrastructure component, the 5461-655 ensures uninterrupted power delivery under demanding industrial conditions.
Selection Background
Industrial buyers sourcing a WOODWARD 5461-655 replacement or equivalent power supply typically face one of three scenarios: an end-of-life unit requiring a direct swap, a system expansion requiring additional power capacity, or a cost-optimization review seeking a functionally equivalent substitute. Understanding which scenario applies determines whether a direct drop-in, a functional equivalent, or a cross-brand alternative is the right path. This guide covers all three, with clear prerequisites and caveats for each option.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
A direct drop-in replacement shares identical form factor, connector pinout, output voltage/current, and firmware interface. The only confirmed direct replacement for the WOODWARD 5461-655 is the OEM unit itself (new, refurbished, or remanufactured). Konmask sources genuine WOODWARD 5461-655 units through authorized and verified supply channels. Prerequisite: Confirm part number label and revision level match your installed unit.
2. Functional Equivalents (Same Brand, Different Revision)
WOODWARD may have issued revised or successor part numbers for the 5461-655 power supply. These functional equivalents typically share the same electrical interface but may differ in firmware revision or minor mechanical dimensions. Prerequisite: Obtain WOODWARD’s official supersession notice and verify compatibility with your system firmware version before substituting. Contact Konmask for cross-reference documentation.
3. Cross-Brand Alternatives
For applications where OEM sourcing is not feasible, third-party power supply modules with matching output specifications (voltage, current, form factor, and connector type) may serve as functional substitutes. Brands commonly evaluated in this context include industrial PSU manufacturers with DIN-rail or rack-mount modules in the same power class. Important caveats: Cross-brand alternatives require full electrical validation, may void OEM warranty, and are not recommended for safety-critical or certified installations without engineering sign-off. Konmask can assist with technical pre-qualification.

Selection Guide
Use these three questions to confirm the right part for your application:
- Is the part number an exact match? Confirm the label on your installed unit reads 5461-655 and note any revision suffix. If a revision suffix differs, contact Konmask to verify interchangeability before ordering.
- Does your system firmware support the replacement unit? Some WOODWARD power supply revisions are tied to specific firmware versions. Provide your controller firmware version to Konmask for cross-reference validation.
- Is your application safety-critical or under regulatory compliance? If yes, only OEM-sourced genuine WOODWARD 5461-655 units with full traceability documentation are appropriate. Konmask can provide certificates of conformance and test reports upon request.

Replacement & Compatibility FAQ
Q1: Can I directly replace the WOODWARD 5461-655 with a third-party equivalent power supply?
A: A third-party substitute may be electrically compatible if output voltage, current, and form factor match exactly. However, WOODWARD systems use proprietary power sequencing and bus architectures, so cross-brand replacements must be fully validated by a qualified engineer before installation. For safety-critical applications, Konmask recommends sourcing the original 5461-655 or a WOODWARD-approved equivalent.
Q2: Is the WOODWARD 5461-655 compatible with all WOODWARD governor systems?
A: The 5461-655 is designed for specific WOODWARD control system platforms. Compatibility depends on the system’s power rail specification and physical form factor. Provide your system model and firmware version to Konmask for a definitive compatibility confirmation before ordering.
Q3: What is the difference between a replacement and a substitute for the WOODWARD 5461-655?
A: A replacement is an identical or OEM-approved unit that installs without modification — the 5461-655 itself (new or refurbished) is the safest replacement. A substitute is a functionally equivalent unit from the same or a different brand that meets the electrical and mechanical requirements but may require engineering validation. Konmask can help identify and qualify both options for your specific application.
