Woodward’s LSM (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
Woodward LSM models are used on engines equipped with speed controls that accept a ±3 Vdc speed setting input, a 0.5 to 4.5 Vdc input, or a PWM (pulse-width-modulated) input. The LSM allows use of Woodward power generation accessories, as well as 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.
This unit is a model of Woodward Inc.'s series of generator regulation and control modules. There are several series available in our inventory of both used and surplus hardware. This unit is classified as a part of the Woodward Load Sharing modules, and designated with the numerical ID of 9907-838. The 9907-838 LSM model is designed to provide the industrial generator system it is attached to with several functionalities and adjustment capabilities. This unit is outfitted with both isochronous and droop load sharing. The Isochronous load sharing is capable of providing the generator an adjustment of the load it has, even when two or more generators are paralleled to it. The specified full load condition is from 3 to7 A Rms. The Droop load sharing is able to provide a reduction of output when both no-load and full-load conditions are implemented. The 9907-838 unit is outfitted to run on a DC power intake, the voltage ranging between 18 and 32 V/DC, minimum to maximum. The environmental specifications for this unit give it an operational temperature range between -40 to 70 degrees Celsius, or -40 to 158 degrees Fahrenheit. The shock it is able to resist rates up to 40 G, at an 11 millisecond sawtooth pulse. The 9907-383 is designed with a standard set of dimensions, making it simple to install into an acceptable unit. The length is 10.77 inches, the width, 8.43 inches, and the height is 2.33 inches. The approximate weight for this unit is 1398 grams.
