The Woodward Load Sharing Module is made for use with Caterpillar engines equipped with a Caterpillar digital speed control with a pulse width modulated (PWM) input. The Load Sharing Module allows use of a Woodward power generation accessories and allows load sharing between the Caterpillar digital speed control equipped engines and engines controlled with Woodward electronic controls.
The Load Sharing Module provides isochronous and droop load-sharing capability for engines equipped with Caterpillar digital controls in generator set applications. Additional equipment in the control system can include the Woodward SPM-A Synchronizer, Paralleling Phase Switch, Import/Export Control, Precision Frequency Control, Automatic Generator Loading Control, and Automatic Power Transfer and Loading Control.
