Woodward 9907-838 Product Introduction
Woodward 9907-838 is a high-reliability load sharing module (LSM) designed for industrial generator systems and engine control applications. It is engineered to optimize the performance of paralleled generator sets by providing both isochronous and droop load sharing capabilities. The isochronous mode ensures equal load distribution among multiple paralleled generators, while the droop mode automatically reduces output under no-load and full-load conditions. This module is compatible with Caterpillar engines equipped with digital speed controls and Woodward power generation accessories, such as the SPM-A synchronizer, enabling seamless integration and reliable operation in harsh industrial, power generation and marine environments.
