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
