Product Overview
The Woodward 8440-1978 is a high-precision Digital Synchronizer and Load Control (DSLC) module designed for industrial generator sets. It automates the synchronization process—matching frequency, phase angle, and voltage between the generator and a bus or utility grid. It also manages proportional load sharing for stable parallel operation. We supply this unit as 100% Brand New original equipment to ensure maximum safety and efficiency in power generation.
