Woodward easyYgen-3500XT 8440-2085 Generator Set Controller
The Woodward easYgen-3500XT (8440-2085, P1 Package) is a high-performance, microprocessor-based genset controller from the easYgen-3000XT series, engineered for complex multi-generator paralleling and power management. It integrates engine control, generator protection, breaker synchronization, and peer-to-peer load sharing into a compact panel-mount unit, featuring a backlit LCD and tactile keypad. Supporting up to 32 gensets and 16 LS-5 breakers via CANopen and redundant Ethernet, it delivers reliable, redundant power management for industrial, marine, and critical infrastructure.
Primary Applications
- Complex Paralleling: Synchronization and load sharing for up to 32 generators across 32 bus segments。
- Utility Intertie: Grid paralleling, islanding, and tie-breaker control for multi-utility feeders。
- Critical Power: Data centers, hospitals, and industrial facilities requiring redundant backup power。
- Marine Power Management: Paralleling of ship generators and shore connection synchronization。
- Distributed Generation: Peak shaving, load sharing, and island-mode operation for industrial microgrids。
