Woodward 9905-797 Digital Synchronizer and Load Control

Overview

The 9905-797 is a Digital Synchronizer and Load Control (DSLC) module by Woodward. It serves as an advanced replacement for the older 9905-361 model. This unit provides robust control for three-phase AC generators, offering both phase matching and slip frequency automatic synchronization. It can also manage VAR/PF and process control, making it versatile for various industrial applications. The unit is compact, reducing installation space and wiring requirements.

The 9905-797 features sensors to monitor RMS power and provides bumpless loading/unloading. Operators can configure it for baseload operation or set power levels for importing/exporting and processing. Additionally, it uses a Local Operating Network (LON) to manage load distribution across multi-engine setups.
