Product Description
Woodward DYN1-10784-003-0-12 Electronic Governor
Product Overview
- The Woodward DYN1-10784-003-0-12 is an Electronic Governor designed for precise speed control of small to medium-sized diesel, gas, or gasoline engines in industrial applications such as generator sets, pumps, compressors, and marine propulsion systems. Part of Woodward’s DYN1 series, this analog governor provides reliable speed regulation and isochronous operation to maintain consistent engine speed under varying load conditions. The DYN1-10784-003-0-12 is configured for 12 VDC operation and includes specific calibration settings for actuator compatibility (denoted by the part number suffix). It features a compact design and robust construction for reliable performance in harsh environments. Compared to Woodward’s digital governors (e.g., 8406-121) or genset controllers (e.g., EasyGen-3500-5, 8440-2087), the DYN1-10784-003-0-12 is a simpler, analog-based solution focused solely on engine speed control, not generator or power management. It is distinct from Woodward’s excitation systems (e.g., DECS-100-B15), transfer switch controllers (e.g., DTSC-200), and actuators (e.g., 8408-921).
