Generator Synchronizing Module WOODWARD 8440-1667

Description

The Woodward 8440-1667 is part of the SPM-D10/XN synchronizer series, engineered for precise and automated synchronization of three-phase AC generators. It continuously monitors voltage, frequency, and phase angle between the generator and the busbar, adjusting the generator’s speed and voltage to match the grid before issuing a breaker close command. This model is especially suited for systems equipped with automatic voltage regulators (AVRs) and speed control modules, whether or not they are Woodward-branded. It supports both analog and PWM outputs, allowing flexible integration with a wide range of control architectures. The unit features a two-line LCD display for real-time status, alarms, and parameter adjustments. Its compact design and rugged construction make it suitable for marine, industrial, and utility applications.
