Description
Product Overview
The Woodward 5417-028 is a high-performance digital load sharing module designed for precision power management in generator set applications. As part of Woodward’s LSM (Load Share Module) series, this advanced control unit enables seamless load sharing between multiple generators in parallel operation, ensuring optimal power distribution and system stability. The 5417-028 combines Woodward’s proven isochronous speed control with sophisticated kW/kVAR load sharing algorithms, making it ideal for mission-critical power generation systems in industrial plants, data centers, and marine applications. Its rugged design features military-grade components capable of withstanding extreme environments (-40°C to +85°C) while maintaining ±0.25% speed regulation accuracy. The module’s dual-microprocessor architecture provides redundant processing for fault-tolerant operation, with automatic bumpless transfer between control modes during grid disturbances or generator failures.

WOODWARD 5417-028
Main Features and Advantages
Advanced load management: The Woodward 5417-028 features cross-current compensation and reactive droop compensation algorithms that maintain stable operation during large load steps. Its adaptive synchronization capability reduces breaker wear by minimizing phase angle differences during generator paralleling.
Multi-language interface: The module’s backlit LCD display supports English, Spanish, French, and Chinese, with intuitive menus for quick parameter adjustment. Password-protected settings prevent unauthorized changes to critical parameters.
Comprehensive diagnostics: Built-in oscilloscope functionality captures and analyzes transient events, while 64-hour trend logging tracks generator performance for predictive maintenance. The 5417-028 automatically detects and compensates for failed speed sensors or signal loss.
Flexible integration: Optional Ethernet expansion card (5417-028-ETH) enables remote monitoring via Woodward’s Navigator software, while standard Modbus RTU allows connection to most SCADA systems. The module’s dual-redundant CANbus ports support Woodward’s EasyGen control systems.
