9905-354 | Woodward Digital Synchronizer and Load Control

Description 

Woodward model 9905-354 is a microprocessor-based DSLC Digital Synchronizer and Load Control, primarily intended for paralleling, synchronizing, loading, and unloading three-phase generator sets in conjunction with a Woodward speed control and an automatic voltage regulator. 

Key functions of the 9905-354 include built-in diagnostics, setup, metering, and diagnostic capability through a handheld programmer terminal, automatic generator loading and unloading, droop, baseload, and isochronous load control capability, and a reverse power relay. 

This control offers phase matching or slip frequency synchronizing, utilizing actual slip frequency and breaker delay values to ensure minimal phase difference between the generator and the bus during breaker closure. It features automatic dead-bus closure functionality, allowing only one DSLC control to initiate dead-bus closing through communication network-based locking techniques.
