Description
Woodward EM3003522-1042
Technical Specifications
- Part Number: EM3003522-1042.
- Type: Excitation Driver / AVR Module.
- Compatibility: EASYGEN-3400/3500XT (Release 1.16+).
- Input: PWM signal from EASYGEN controller.
Functional Features
- Active Voltage Regulation: Precise control of generator field current.
- Soft Start: Gradual voltage build-up to prevent mechanical stress.
- Volt/Hz Protection: Under-frequency roll-back to prevent core saturation.
- Thermal Protection: Automatic shutdown on over-temperature.
Application Scenarios
Used in generator sets requiring precise voltage control, power factor regulation, and fault ride-through capabilities.
Performance Parameters
- Excitation Power: Sized for specific generator field requirements.
- Response Time: Fast AVR response for transient stability.
Material Composition
High-power electronic components with heat sinks and conformal coating.
Structural Characteristics
- Mounting: Panel or chassis mount with heat dissipation fins.
- Connections: High-current terminals for field output.
Working Principle
Receives a PWM command from the EASYGEN controller, converts it to a regulated DC field current, and continuously adjusts to maintain the desired generator voltage.
Installation Requirements
Provide adequate cooling airflow around the heat sink. Use properly sized field cables to minimize voltage drop.
Precautions for Use
Never operate without proper over-temperature protection. Verify field winding resistance matches module specifications.
