Woodward Synchronizer


    Woodward’s SPM-A speed and phase matching synchronizer provides automatic frequency and phase matching when used with 2301, 2301A, and EPG (Electrically Powered Governor) electric load sharing control systems.

    Features include: 

    • Automatic synchronization of generators
    • Adjustable dynamics
    • Frequency, phase, and optional voltage matching
    • Selectable match-up time
    • Automatic circuit breaker closure
    • Selectable output impedance
