Woodward9905-002|SPM-A Synchronizer Module
Woodward 9905-002 SPM-A Synchronizer Module
Description
Woodward 9905-002 is a 50/60 Hz synchronizer module with voltage matching, designed for generator paralleling applications requiring precise frequency, phase, and voltage synchronization.
Features
- Includes voltage matching function
- Phase-locked-loop control for accurate synchronization
- Supports single- and multi-unit generator synchronization
- Offers high, low, or EPG output compatibility
- Factory-configurable dwell time and phase window settings
Technical Specifications
- Frequency Range: 50/60 Hz
- Phase Window: ±10°
- Voltage Matching Tolerance: 1% standard
- Input Voltage: 120 Vac or 208/240 Vac
- Dwell Time Options: 1/8, 1/4, 1/2, or 1 second (factory set to 1/2 second)
- Output Types: High impedance, low impedance, or EPG
- Breaker Closure Signal: Relay contact closure when phase, frequency, and voltage are within limits
- Speed Bias Output: Proportional correction signal based on phase difference
- Operating Principle: Compares generator and bus signals via phase detector and voltage comparator
- Lockout Function: Disables synchronizer for 1 second after closure command; auto-resets when phase exceeds window
