Description
Need to manage load distribution and speed regulation across multiple prime movers? The Woodward 9907-023 is an analog 2301A series module built for isochronous or droop speed control and automatic load sharing. This unit interfaces directly with a magnetic pickup (MPU) to monitor engine speed, regulating generator outputs to ensure a balanced distribution of kilowatts across a shared electrical bus.

On recent multi-generator synchronization projects, balancing active power across mismatched engines can be a challenge. The 9907-023 simplifies this by incorporating an internal load sensor that measures generator current and voltage via external potential and current transformers. This enables the control card to calculate the real power (kW) and adjust the actuator output dynamically, preventing one generator from motoring the other.
Woodward 9907-023 Technical Specifications
Verify your potential transformer (PT) ratios and current transformer (CT) secondary outputs against the Woodward installation manual 82020 before field deployment.

The module mounts vertically or horizontally within a standard electrical control panel. Honestly, don’t underestimate the phase alignment of your CT and PT connections. In my experience, swapping the polarity of a single current transformer line on the terminal strip will cause the module to read negative power—which makes the engine run away or trip immediately on reverse power during synchronization. Double-check your phase rotations before closing the breaker.
International Shipping & Logistics Optimization
Moving critical power-generation components across international borders requires rigorous logistics handling to ensure swift port clearance. Here is our global distribution strategy for this module:
-
Export Compliance: The Woodward 9907-023 is classified under standard power management and industrial governance codes. It carries a Harmonized System (HS) Tariff Code of 8537.10.91. We prepare all necessary commercial invoices, standardized packing lists, and export declarations to prevent customs delays.
-
Logistics Options: When a vessel or a backup power plant is down due to a governor fault, shipping speed is paramount. We handle urgent shipments through DHL Express, FedEx Priority, and UPS Worldwide Saver. Average transit times to North America, Western Europe, and major maritime hubs in Asia are 2 to 4 business days.
-
Incoterms and Risk Allocation: Our standard transaction terms are EXW (Ex Works) or FCA (Free Carrier). Under FCA, we complete the domestic export customs clearings at our regional hub and hand the package to your specified global carrier, smoothly transferring transit risk to your corporate insurance policy.
-
Payment Terms: For commercial trade flexibility, we accept corporate bank wire transfers (T/T), verified third-party industrial escrow, and irrevocable Letters of Credit (L/C) for complex microgrid upgrades or regional distribution projects.
Frequently Asked Questions Regarding 9907-023
-
What is the main difference between the 9907-023 and the 9907-028 model?
Well, technically it comes down to power input and functionality. The 9907-023 is a low-voltage DC-powered unit (20 to 40 VDC) that features active load sharing, whereas the 9907-028 is a high-voltage AC/DC unit configured mainly for standalone speed control.
-
Can this module handle parallel operation with the utility grid?
Yes, but you must switch the module into droop mode rather than isochronous mode. Running in isochronous mode against an infinite utility grid will cause the actuator to saturate to maximum or minimum fuel instantly.
-
How is the unit protected against international shipping damage?
Each card is enclosed in a thick, factory-sealed static-shielding bag, cushioned by custom-cut shock-absorbent foam inserts, and enclosed in a double-walled rigid industrial carton to withstand long-haul air transport.
