Description
Woodward SPM-D2-1010B/YB
Technical Specifications
- Model: SPM-D2-1010B/YB
- Measurement: Three-phase / Four-wire
- Outputs: Discrete speed and voltage raise/lower
- Power: Wide-range AC/DC or 24 Vdc
Functional Features
- Synch-Check: Verifies that all synchronization criteria are met before permitting breaker closure.
- Adjustable Deadbands: Configurable frequency and voltage control deadbands to prevent hunting.
- ToolKit Support: Full parameter configuration via USB.
Application Scenarios
Used in cogeneration plants, hospital backup power systems, and data centers where precise three-phase synchronization is critical for protecting sensitive equipment.
Performance Parameters
- Operating Temperature: -20°C to 70°C.
- Storage Temperature: -30°C to 80°C.
- Rated Voltage: 230/400V AC (max 300V AC).
Material Composition
Conformal-coated PCBs for protection against humidity, salt spray, and chemical vapors in industrial environments.
Structural Characteristics
- Front Panel: Integrated synchronizing oscilloscope and LED status indicators.
- Connectors: Secure screw-type or plug-in terminals for field wiring.
Working Principle
Continuously compares the three-phase generator output with the three-phase bus. It issues corrective raise/lower signals to the governor and AVR until the voltage, frequency, and phase angle of all three phases are within the preset tolerance window.
Installation Requirements
Provide adequate ventilation around the unit. Ensure all grounding connections are secure to maintain electrical safety and signal integrity.
Precautions for Use
Do not exceed the maximum surge voltage rating. Always use properly rated fuses or circuit breakers on the voltage sensing inputs.
