Overview
The Woodward 9905-797 DSLC combines synchronizer and load control functions into a single module, simplifying generator set automation. It ensures bumpless load transfer, isochronous load sharing, and dead bus closing capabilities, making it ideal for complex multi-generator installations.
The DSLC also supports process import/export control and can maintain either power factor or VAR control, depending on system requirements. It integrates seamlessly with other Woodward controllers, enabling flexible expansion and reliable communication with SCADA/DCS systems.
