WOODWARD 8440-1546H Synchronizer Governor/Control Unit
1. Product Description
The WOODWARD 8440-1546His a high-performance synchronizer governor designed for generator set control in power generation and distributed energy systems. As part of Woodward’s SPC-D2 series, it ensures precise synchronization, load sharing, and protection for diesel, gas, or steam turbines. Key features include slip-frequency synchronization with phase/voltage matching, soft unloading, and dual-language support (English/German). With password protection and configurable settings via HMI or Woodward’s USB toolkit, the 8440-1546H offers flexibility for complex applications while reducing downtime through online configuration.
