SPM-D11 Series
Comprehensive synchronizer and load share unit
Our new drop-in replacement, the SPM-D2-11 series is the successor to the SPM-D11 products.
The SPM-D11 Series are microprocessor-based synchronizers designed for use on one- or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D11 Series synchronizers provide automatic frequency, phase, and voltage matching, using either analog or discrete output bias signals. It combines synchronizing for one circuit breaker, load and power factor control, or isochronous load sharing and generator protection.
Features include:
- Synchronization for one circuit breaker
- Phase match or slip frequency synchronization with voltage matching
- Outputs for speed and voltage bias signals
- Active power and power factor control
- Two analog load share lines for active and re-active power load sharing
- Analog input to control active power set point externally
- Generator protection included
- Discrete inputs for operating mode selection
- Two-line liquid crystal text display for operation, alarm indication, and visualization of measuring values
- LED synchroscope
- PC and front panel configurable
