Description

Short Description

The Woodward 9907-173 Load Sharing Module (LSM) is a high-precision control device designed for parallel generator systems. It accurately distributes real (kW) and reactive (kVAR) loads, ensuring stable operation, synchronization, and overload protection in industrial power applications.

Key Features

• Supports both isochronous and droop load sharing modes

• Accurate kW and kVAR measurement using 3-phase CT and PT inputs

• Compatible with ±3 VDC, 0.5–4.5 VDC, and PWM control signals

• Designed for generator synchronization in parallel systems

• Rugged construction with 40 G shock resistance

• Wide operating temperature range (–40°C to +60°C)

• Reverse voltage and under/over-voltage protection

• Low power consumption for efficient integration
