Technical Specifications & Selection Guide

Selection Guide: The 9905-973 is recommended for applications requiring automatic generator-to-generator or generator-to-grid synchronization with active/reactive load sharing. Verify your bus voltage range and communication protocol requirements before ordering. Contact our engineers for compatibility confirmation with your existing Woodward control architecture.

Typical Application Scenarios

✅ Data Centers & Critical Facilities: Uninterrupted power is non-negotiable. The 9905-973 enables seamless automatic paralleling of standby generators, ensuring zero-gap power transfer during utility outages — a capability that protects sensitive IT infrastructure from costly downtime.

Marine & Offshore Platforms: Harsh sea environments demand robust, vibration-resistant control hardware. The IP54-rated front panel and wide operating temperature range (-40°C to +70°C) make the 9905-973 a proven choice for offshore drilling rigs and vessel power management systems.

✅ Oil & Gas Processing Plants: In upstream and midstream facilities, generator reliability is tied directly to production continuity. The heavy-duty DSLC module supports isochronous and droop control modes, adapting to variable load profiles common in compressor and pump-driven processes.

Utility Peaking & Power Plants: Grid-tie synchronization demands precision. The ±1° phase angle accuracy of the 9905-973 ensures compliant, low-transient breaker closure — meeting utility interconnection standards and protecting rotating equipment from mechanical shock.

✅ Hospitals & Healthcare Facilities: Life-safety systems require generator paralleling that is both fast and fault-tolerant. The 9905-973’s built-in protection suite (reverse power, over/under voltage, loss-of-synchronism) provides the multi-layer safeguards mandated by healthcare electrical codes.

Core Features & Technical Advantages

• Precision Automatic Synchronization: Matches voltage, frequency, and phase angle before breaker closure — eliminating electrical transients and mechanical stress on generator windings.
• Proportional kW & kVAR Load Sharing: Distributes active and reactive loads across paralleled units with ±2% accuracy, optimizing fuel consumption and extending alternator life.
• Multi-Mode Control Flexibility: Supports isochronous, droop, and base load strategies — configurable to match diverse grid and island-mode operational requirements.
• Robust Protection Suite: Integrated reverse power, over/under voltage, over/under frequency, and loss-of-synchronism protection — all configurable via front-panel keypad.
• Modbus RTU / RS-485 Connectivity: Native SCADA integration capability enables remote monitoring, parameter adjustment, and alarm management without additional gateways.
• Heavy-Duty Industrial Build: Rated for -40°C to +70°C operation with IP54 ingress protection — engineered for continuous duty in demanding industrial and marine environments.
