Reviews For 9907-029
Internal Review
(5.0)
The Woodward SPM-A Synchronizer (9907-029) is an advanced module within the SPM-A line, expertly designed for precise frequency and phase parallelism and speed biasing in turbine and engine applications. Its key strength lies in its fully adjustable parameters and dynamics, allowing for tailored performance depending on engine size—faster for smaller units and slower for larger turbomachinery like diesel, gas, and steam turbines.
Versatile Performance and Robust Specifications: Operating within a 50-60 Hz frequency range and featuring a flexible phase angle limit of ±10 degrees, the 9907-029 also includes 1% voltage matching capabilities. It accepts 115-230 VAC inputs with ±10% tolerance and consumes only 5W. The unit's outputs are engineered with both high and low impedance for broad load-sharing compatibility (2301 and 2301A/EPG/2500 systems). – AX Control Technician
