Woodward understands the time-intensive nature of Power Generation projects. Ensuring the longevity of components is one way we can make our customers successful. Woodward has supplied and supported the well-established SPM-D line of synchronizers for 20+ years. With the state of the art Drop-In replacement successor, SPM-D2 the life of this synchronizer line is now extended.

All of the SPM-D2 synchronizers are password protected and are configurable either through HMI as before or through ToolKit configuration tool with USB connectivity. The SPM-D2-11 is a microprocessor-based synchronizers designed for use on two or three phase
AC generators equipped with Woodward or other compatible speed controls and automatic voltage

The SPM-D2-11 synchronizer provides 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. This
synchronizer is applied to a wide range of prime movers and generators, as its control signals may be set to fit several types of gensets – from fast reacting diesel engines to soft reacting gas turbines.

The SPM-D2-11 synchronizer is available in 1 base model:
SPM-D2-11 …/LSXR: provides 1-phase / 2-wire voltage measurement with analog or discrete biasing signals, analog active and reactive load sharing lines, and generator protection.
