8440-2165 | Woodward | SPM-D Synchronizer

Description

The Woodward 8440-2165 SPM-D Synchronizer is an industrial control component designed for power system synchronization applications. As part of Woodward’s SPM-D synchronizer line, it leverages proven microprocessor-based technology to deliver precise, reliable control for single-phase or three-phase AC generators paired with compatible speed controls and automatic voltage regulators. Core functions include automatic frequency, phase, and voltage matching, ensuring seamless alignment between offline generators and existing power systems. Once parameters fall within specified limits, the unit sends a contact closure signal to trigger breaker activation, enabling safe, stable generator connection. Like other Woodward synchronizer models, it may feature user-adjustable dynamic response settings to match different equipment requirements: fast response for small to medium diesel engines, and slow response for large diesel, gas, or turbine machinery. It supports integrated control capabilities, including breaker synchronization, load sharing, and power factor management, to optimize overall power system performance. Operating modes typically include RUN, CHECK, PERMISSIVE, and OFF, providing flexible operation for various industrial power control scenarios. This synchronizer plays a critical role in preventing power disturbances and ensuring consistent, safe operation of industrial power equipment.
