8440-1667 Woodward | Generator Sync System with LED Display

Product Overview

The 8440-1667 (Model: 8440-1667 D) is a precision microprocessor-based synchronizer belonging to the Woodward SPM-D10 series. Specifically designed for three-phase AC generators, this synchronizing system provides automated frequency, phase, and voltage matching between a generator and a busbar (or between two buses). The 8440-1667 (Part Number: 8440-1667) is an essential component for power generation facilities, ensuring that circuit breakers are closed only when the electrical parameters are within safe, synchronized limits.

Engineered for high-reliability environments, the 8440-1667 (Order Number: 8440-1667) features a clear LED display for real-time parameter monitoring and intuitive configuration. It supports two-phase or three-phase sensing (system dependent) and is capable of handling auxiliary power inputs up to 250 V AC/DC. Its robust design is widely utilized in emergency standby power, cogeneration plants, and marine power management systems where Expertise and Trustworthiness in grid coupling are paramount.
