Product Description
WOODWARD 9907-173
The Woodward 9907-173 Load Sharing Module is designed for use with Woodward electronic governors and prime mover controls that have a load sharing input. This module facilitates precise isochronous load sharing among multiple generator sets operating in parallel. It accurately measures the true RMS power of the generator and provides a proportional DC signal to the governor system, enabling balanced load distribution and stable operation. The 9907-173 is commonly used in applications requiring parallel operation of generators, such as in power generation plants, marine propulsion systems, and various industrial settings to optimize performance and ensure system stability.
