Overview
The Woodward 9905-795 DSLC is a microprocessor‑based controller designed for three-phase AC generator systems, combining synchronizer and load control functions into a single unit. It provides automatic synchronizing, bumpless load transfer, isochronous load sharing, and reactive power management.
The DSLC also supports dead bus closing and process import/export control, making it ideal for complex multi-generator installations. It integrates seamlessly with other Woodward controllers, enabling flexible expansion and reliable communication with SCADA/DCS systems.
