Overview

The Woodward 9907‑004 MSLC is a microprocessor‑based synchronizer and load controller. It 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 4‑wire wye, 120 V systems, while related models (9907‑005 and 9907‑006) are intended for other wiring/voltage configurations.
