Genuine Woodward 9905-463 Speed Control Module | EG3P Series – Verified Source
The Woodward 9905-463 is a precision-engineered Speed Control Module at the heart of turbine governor and engine management systems across power generation, oil & gas, and marine propulsion industries. As a legacy Woodward EG3P-series component, this module is no longer in active mass production — making sourcing from a verified, trustworthy supplier absolutely critical. The market for discontinued Woodward control modules is unfortunately rife with counterfeit boards, refurbished-as-new units, and grey-market parts that carry no traceability, fail under load, and void OEM warranties.
At Konmask, every Woodward 9905-463 we supply is sourced through documented, traceable channels and subjected to our in-house 4-step verification protocol before dispatch. We do not list what we cannot verify. Our commitment to genuine, authentic components means you receive a product with full traceability — not a gamble. Buyers consistently confirm our parts as verified originals upon installation and third-party bench testing.

Our 4-Step Quality Verification Process
- Step 1 — Visual & Cosmetic Inspection: Each unit is examined under magnification for board damage, solder joint integrity, component substitution, counterfeit markings, and tamper evidence. Original Woodward labeling, part number silk-screen, and date codes are cross-referenced against known-authentic samples.
- Step 2 — Functional Bench Test: The module is powered at rated voltage and its speed signal response, actuator output linearity, and droop/isochronous switching are verified using calibrated test equipment. Results are logged and available as a Test Report upon request.
- Step 3 — Traceability Documentation: We provide a Certificate of Conformance (COC) stating part number, serial/batch reference, condition, and sourcing declaration. Country of Origin (COO) Declaration and Packing List are included with every shipment.
- Step 4 — Pre-shipment Packaging Audit: Units are packed in anti-static bags, foam-lined boxes, and outer cartons with moisture-barrier desiccant. Photographic evidence of the packed unit is available upon request before dispatch.
Key Features & Benefits
- Isochronous & Droop Control Modes: Supports both zero-droop isochronous operation and adjustable droop (0–10%) for load sharing — compliant with ISO 8528-5 generator set performance standards.
- Wide MPU Input Range: Accepts magnetic pickup signals from 100 Hz to 10,000 Hz, compatible with a broad range of engine flywheel tooth counts without additional signal conditioning.
- Robust Industrial Design: Rated for -40°C to +70°C ambient operation, meeting IEC 60068-2 environmental stress requirements for industrial control equipment.
- Fast Governor Response: Sub-100ms speed correction response time minimizes transient speed deviation during sudden load application or rejection.
- Direct Actuator Compatibility: Proportional mA output directly drives Woodward EG3P and compatible third-party actuators without intermediate signal converters.
- Documented Traceability: Every unit ships with COC, COO Declaration, and optional Test Report — meeting procurement compliance requirements for power utilities, EPC contractors, and OEM service teams.
Typical Applications
- Power Generation: Diesel and gas genset governor control in standby and prime power plants (50/60 Hz grid-parallel and island mode)
- Oil & Gas: Wellhead compressor engine speed regulation and pipeline pump drive control in upstream and midstream facilities
- Marine Propulsion: Main engine and auxiliary generator speed governing on commercial vessels and offshore platforms
- Industrial Turbines: Steam turbine speed control in process industries including petrochemical, pulp & paper, and sugar refining
- Mining & Heavy Equipment: Large diesel engine governor replacement and retrofit in mining haul trucks and drilling rigs
- OEM Service & MRO: Spare parts inventory for Woodward-equipped OEM machinery requiring like-for-like authentic replacement modules
