Product Description: Woodward 5462-529 Digital Speed Control & Synchronization Integrated Controller

Product Model: 5462-529

Brand: Woodward

Series: Flex500 5462 Series

Type: Integrated Speed Regulation for Generator Sets + Automatic Grid Connection Synchronization Controller

I. Product Overview

The 5462-529 integrates engine / turbine speed control + fully automatic synchronous grid connection dual functions. It is suitable for diesel, gas, and steam turbine generator sets, and simultaneously performs speed stabilization control, load distribution, precise voltage/frequency/phase synchronization, and shock-free closing. This one-module replaces independent speed regulators + synchronizers, simplifying the power station control system architecture.
