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).

　　Product Description

Unit 9907-252 is available from our inventory here at AX Control Inc. The 9907-252 Load Sharing Module is powered by a supply intake that nominally rests at 24 volts of direct current but ranges from at least 18 to 32 V/DC. The inputs for this unit are both three-phase PT and CT inputs. The PT inputs range from a voltage of 95 to 130 V/AC, line to line. The CT inputs need between 3 and 7 A Rms at a full load.

The adjustments available for this unit to be able to process include droop and load gain. Droop is able to provide output reduction between no-load and full-load. The Load Gain adjustment alters the load on an individual generator when two or more are paralleled. The environmental specifications that the 9907-252 makes it best suited to work in an environment that are stable and between -40 to 70 degrees C, or -40 to 158 degrees F. AX Control Inc. is prepared to buy and repair such machines. AX Control can and will, sell and resell these machines.

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
