Configured for frequency and phase matching in generator control networks, the Woodward 9905-001K (SPM-A Digital Synchronizer) provides direct physical/electrical execution. The unit continuously monitors the voltage, frequency, and phase relationships between an offline generator and a live busbar or target generator. Upon achieving alignment within defined thresholds, it issues a discrete breaker close command to enable parallel bus connection without current surges or mechanical shaft stress.

The Woodward 9905-001K integrates direct analog interface circuitry to evaluate potential transformer (PT) signal inputs from both generator and bus sources. Its internal discriminator computes phase angle error and velocity differentials to optimize actuator loop feedback response. Speed adjustment signals are output directly to compatible speed controls, such as EPG series governors, adjusting prime mover speed to achieve dynamic synchronization prior to breaker closure.
Q: How is input voltage selection configured on the Woodward 9905-001K unit?
A: Terminal jumper arrangements allow selection between 115 VAC RMS and 230 VAC RMS potential transformer operating ranges within a +/-10% tolerance band.
Q: What output modes are supported for interface with prime mover governors?
A: The device provides discrete high-impedance, low-impedance, and EPG-compatible output configurations to interface directly with dynamic speed control loops.
Q: What are the physical mounting orientation requirements for shock and vibration compliance?
A: The module must be rigidly fastened via its panel-mount chassis cutout to ensure vibration attenuation up to 0.7 g across the 13.2 Hz to 150 Hz spectrum.
