Woodward 8440-1713 SPM-D11 Synchronizer

Quantity

Manufacturer: Woodward
Model/Part Number: 8440-1713
Description: SPM-D11 Microprocessor-Based Synchronizer, 1-Phase Measuring Inputs, 100 VAC, 5 A CT, Analog/Discrete Bias Outputs, for AC Generator Synchronization

The Woodward 8440-1713 is part of the SPM-D11 series, a microprocessor-based synchronizer designed for synchronizing one- or three-phase AC generators with a bus or utility grid. It is compatible with Woodward and other speed controls and automatic voltage regulators (AVRs), providing automatic frequency, phase, and voltage matching using analog or discrete output bias signals. The unit is suitable for a range of prime movers, including diesel engines and gas turbines, in power generation and industrial applications.
