Woodward 8446-1040 LS-5 Circuit Breaker Controller

Woodward 8446-1040 LS-5 Circuit Breaker Controller Overview

The Woodward 8446-1040 LS-5 Series Circuit Breaker Controller delivers precision synchronization and intelligent load sharing for generator sets operating with easYgen-3000XT control systems. Engineered for mission-critical power distribution environments, this controller ensures seamless paralleling operations while maintaining optimal load balance across multiple generating units.

Technical Specifications

• Operating Voltage: 12/24 VDC dual-range compatibility
• Control Interface: Integrated with easYgen-3000XT platform
• Synchronization Accuracy: ±5 electrical degrees
• Load Sharing Precision: ±2% of rated load
• Response Time: <100ms for breaker operations
• Operating Temperature: -40°C to +70°C
• Protection Rating: IP20 enclosure standard
• Communication Protocol: CAN bus J1939 compatible

Application Scenarios

Data Center Redundancy: Deploy the 8446-1040 in N+1 generator configurations where uninterrupted power transfer between utility and backup sources demands microsecond-level synchronization precision.

Industrial Cogeneration Plants: Coordinate multiple generator sets in parallel operation, automatically distributing kW and kVAR loads while preventing reverse power conditions that could damage prime movers.

Marine Propulsion Systems: Manage shipboard power generation with automatic load shedding during peak demand events, ensuring critical navigation and safety systems maintain continuous operation.

Microgrid Integration: Enable islanded operation mode with seamless transition between grid-connected and standalone power generation, maintaining frequency and voltage stability throughout switching events.

Solution Benefits

The LS-5 controller eliminates manual synchronization procedures through automated phase-angle matching and voltage regulation. Real-time load monitoring prevents generator overload while optimizing fuel efficiency across paralleled units. Built-in diagnostics provide early warning of breaker contact degradation and control circuit anomalies before they escalate into system failures.

Frequently Asked Questions

Q: Can the 8446-1040 operate with non-Woodward generator controllers?
A: The unit is specifically designed for easYgen-3000XT integration. Third-party controller compatibility requires custom CAN bus mapping and is not officially supported.

Q: What's the maximum number of generators this controller can synchronize?
A: The LS-5 supports up to 32 generator sets in a single paralleling bus when networked through the easYgen control architecture.

Q: Does the controller handle automatic transfer switch (ATS) coordination?
A: Yes, the 8446-1040 includes programmable logic for ATS sequencing, including utility failure detection and generator-to-load transfer timing.

Q: What maintenance intervals are recommended?
A: Perform quarterly inspection of breaker auxiliary contacts and annual calibration verification of synchronization parameters. Firmware updates should be applied as released by Woodward.
