The 8440-1706 B combines synchronizing functionality for one circuit breaker with load and power factor control or isochronous load sharing, supporting seamless operation between multiple gensets or paralleling with the mains. It offers configurable start/stop sequencing, slip frequency and phase matching synchronization for breaker control, and precise real power and reactive power regulation. This controller supports asynchronous (induction) generator operation and offers flexible load dependent start/stop logic to optimize fuel efficiency and system stability. The device is designed to interface with engine control units (ECUs) and auxiliary equipment to provide full system coordination.
Technically, the Woodward 8440-1706 B module measures roughly 144 x 72 x 122 mm and weighs about 800 grams. It includes a two-line LCD display for diagnostics and alarm management, offering users clear system status and fault indications. Operating temperature ranges from -40°C to +70°C allow use in harsh industrial environments. It supports configurable isolated digital inputs and outputs and incorporates programmable protection functions and control logics for versatile installation. Power consumption is optimized for typical 12/24 V DC power systems. Communication options cater to integration within larger control architectures needing responsive and reliable generator synchronization and load sharing.
