Woodward 9907-838 Load Sharing Module

Overview

The 9907-838 is a Woodward Load Sharing Module (LSM) designed to provide precise load distribution and control for industrial generator systems. It incorporates both isochronous and droop load sharing capabilities, ensuring smooth load balancing when multiple generators are in operation.

• Isochronous load sharing allows for load adjustments even when generators are paralleled.
• Droop load sharing offers load reduction from no-load to full-load conditions.

This module is designed for durability and operational reliability in harsh environments, with features that include shock resistance, wide temperature tolerance, and compact dimensions for easy installation.
