　　Product Description

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 Droop load sharing is able to provide a reduction of output when both no-load and full-load conditions are implemented.

 

The specified full load condition is from 3 to7 ARms. 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. It is able to resist a shock that 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 is 8.43 inches, and the height is 2.33 inches. The approximate weight for this unit is roughly 3 pounds. It is crucial to install this machine in a humidity-free zone as well as an area that is primarily dust free. Lastly, AX Control INC. is fully equipped to buy, sell, resell, and repair such machines and the like. 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, AGLC (automatic generator loading control), and APTL (automatic power transfer and loading control).

 

FEATURES & FUNCTIONALITY

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.

Features include:

Load sharing with Woodward and non-Woodward equipped engines

Isochronous and droop load

Easy to setup

Load Sharing Module, Pulse Width Modulated Output, Power Supply 24 VDC, Caterpillar PWM Output Surge Protection Features: • 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 Woodward power generation accessories and allows load sharing between the Caterpillar digital speed control equipped engines and engines controlled with Woodward electronic controls. • Isochronous and droop load sharing • Easy to setup • EC Compliant • UL/cUL Listed
