Product description

Overview

The Woodward 8273-138 Digital Load Sharing Speed Control delivers precise governor control for engine-driven generator systems.
This controller manages engine speed and real power sharing across multiple generator sets operating in parallel.
It combines digital processing accuracy with proven Woodward load sharing algorithms developed for demanding industrial environments.
Moreover, the unit supports stable frequency control during grid-connected or isolated bus operation.
Engineers rely on this module when predictable load distribution and fast transient response are critical.

Designed for industrial power applications, the 8273-138 integrates seamlessly into modern genset control architectures.
Therefore, it serves as a reliable upgrade for legacy analog governors and aging load sharing systems.
