    The SPM-D21 Series consists of microprocessor-based synchronizers designed for use on three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D21 Series provides automatic frequency, phase and voltage matching using either analog or discrete output signals. It combines synchronizing for a GCB (generator circuit breaker) and a MCB (mains circuit breaker), load and power factor control, and generator and mains protection.

    Features include:

    • Synchronization for one or two circuit breakers
    • Phase match or slip frequency synchronization with voltage matching
    • Outputs for speed and voltage bias signals
    • Active power and power factor control
    • Analog input to control active power set point externally
    • Generator and mains protection included
    • Discrete inputs for operating mode selection
    • Two-line liquid crystal text display for operation, alarm indication, and visualization of measuring values
    • LED synchronoscope
    • PC and front panel configurable
