Overview

The Woodward 9907‑005 MSLC is part of the Master Synchronizer and Load Control family. It is a microprocessor‑based device that ensures safe paralleling of generators to a bus by automatically matching frequency, phase, and voltage. Once synchronized, it manages load distribution across multiple generators.

This model is specifically designed for 3‑wire delta, 120 V systems, while related models (9907‑004 and 9907‑006) are intended for other wiring/voltage configurations.
