5441-693 | Woodward Digital Synchronizer Module 100-150VAC

Woodward 5441-693 Digital Synchronizer and Sync-Check Module

The 5441-693 (Model: 5441-693) is a precision-engineered digital synchronizer module within Woodward’s specialized Sync-Check series. It is designed to facilitate the safe and automatic paralleling of a generator with a utility grid or another live bus. By continuously analyzing electrical parameters, the 5441-693 (Part Number: 5441-693) ensures that the generator’s voltage, frequency, and phase angle are perfectly matched before issuing a breaker closure command, effectively preventing catastrophic out-of-phase synchronization.

This module is an essential safeguard in power generation environments, providing high-accuracy monitoring of the voltage slip and phase window. The 5441-693 (Model: 5441-693) operates with a response delay of less than 50 ms, meeting the rigorous IEEE C37.106 standards for synchronization hardware. Its compact design and RS-485 communication capabilities make it an ideal choice for both new control cabinet installations and the retrofitting of legacy turbine and engine governor systems.

Detailed Technical Specifications

The 5441-693 (Model: 5441-693) provides high-fidelity sensing and deterministic relay outputs for critical breaker control.
