General Information
Introduction
The Woodward Load Sharing Module is made for use with engines equipped with speed controls that accept a 0–5 Vdc speed setting. The Load Sharing Module allows use of Woodward power generation accessories and allows load sharing between engines equipped with speed controls that are not manufactured by Woodward and engines controlled with Woodward electronic controls, or controls using other Woodward load sharing modules.
Description
The Load Sharing Module provides isochronous and droop load-sharing capability for engines in generator set applications. Additional equipment in the control system can include the Woodward SPM-A Synchronizer, Import/Export Control, Automatic Generator Loading Control, and Automatic Power Transfer and Loading Control.
Specifications
|
POWER SUPPLY |
