製品紹介
The Woodward 9905-068 Load Sharing Speed Controller is an advanced component engineered to manage both speed control and load distribution among generator sets operating in parallel. As part / Woodward’s industry-leading range / load-sharing and synchronizing equipment, this controller ensures precise regulation / engine or turbine speed while balancing the load between generators for optimal system stability.
The 9905-068 combines the functions / a traditional speed governor with those / a synchronizer and load-sharing 台, /fering integrated control in a single robust platform. It is particularly suited for applications where generators must operate seamlessly on an isolated bus or synchronize with utility power. Designed for both analog and digital interfacing, it supports droop and isochronous load sharing, automatic frequency regulation, and breaker control functions.
Built to perform in demanding industrial and marine environments, the controller helps extend equipment life, reduces fuel consumption, and ensures uninterrupted power delivery through intelligent generator management.
