Woodward 9905-387 ProAct Digital Driver & 2301D Speed Control Unit

The 9905-387 (Model: 9905-387) is a high-performance digital control module from the Woodward 2301D ProAct series, specifically engineered for the precise regulation of industrial engines and turbines. This versatile unit functions as both a speed controller and a driver, providing the logic necessary for isochronous or droop speed control, as well as the electrical output required to interface with ProAct actuators. The 9905-387 (Part Number: 9905-387) is critical for systems requiring complex load sharing and parallel generator operation.

Designed for mission-critical availability, the 9905-387 (Model: 9905-387) incorporates advanced digital filtering to process magnetic pickup (MPU) signals accurately, even in electrically noisy environments. It allows for seamless integration with Woodward accessories such as SPM-A synchronizers and AGLC (Automatic Generator Loading Controls). The unit’s robust digital architecture ensures that once parameters are set, they remain stable without the "drift" common in older analog governors, making it a cornerstone for power generation, marine propulsion, and heavy industrial mechanical drives.
