Overview

The Woodward 9905‑895 DSLC provides automatic synchronization, load control, and protection for generator sets. It ensures that generators can be safely paralleled to a bus by matching frequency, phase, and voltage, and then distributes load across multiple units.

Although now considered obsolete, the 9905‑895 remains widely recognized for its reliability and is often replaced by newer DSLC‑2 models.
