Woodward 8440-2166 SPM-D2-10 Synchronizer
- Manufacturer: Woodward
- Model/Part Number: 8440-2166
- Description: SPM-D2-10 Microprocessor-Based Synchronizer, 3-Phase AC Generator Control, Analog/Discrete Bias Outputs, for Diesel and Gas Turbine Gensets
Overview
- The Woodward 8440-2166 is part of the SPM-D2-10 series, a microprocessor-based synchronizer designed for three-phase AC generators equipped with Woodward or compatible speed controls and automatic voltage regulators. It provides automatic frequency, phase, and voltage matching, ensuring seamless paralleling of generators with a bus or utility grid. Suitable for a wide range of prime movers, from fast-reacting diesel engines to soft-reacting gas turbines, it is used in power generation, industrial, and marine applications. The SPM-D2-10 series serves as a drop-in replacement for the legacy SPM-D line.
