Woodward Synchronizer with Reliability
The SPM-D10 Series are 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-D10 Series synchronizers provide automatic frequency, phase, and voltage matching, using either analog or discrete output bias signals.
Features include:
- Synchronization for one circuit breaker
- Phase match or slip frequency synchronization with voltage matching
- Outputs for speed and voltage bias signals
- Mains protection available in special versions
- Discrete inputs for operating mode selection
- Two-line liquid crystal text display for operation, alarm indication, and visualization of measuring values
- LED synchronoscope
- Wide range power supply option available
- PC and front panel configurable
