Description
The Woodward 9907-029 is a high-performance SPM-A synchronizer/speed and phase matching control module designed for parallel operation of multiple generators or turbines. It ensures precise phase, speed, and frequency matching between units, improving system stability and safety. The module supports standard AC voltage input (115/230VAC, 50/60Hz), with a typical synchronization time of less than 5.5 seconds and a ±10° phase matching window. It features a speed bias output, enabling ±1.5Hz frequency adjustment at 50 or 60Hz generator frequencies, and supports various electronic load sharing control systems, including high-impedance, low-impedance, and EPG outputs.
The 9907-029 consumes as little as 5W, features an indicator light to show its active status, and supports remote mode switching (run, check, enable, and shut-off modes). Its compact size and approximately 2kg weight allow for installation within switchgear. Operating in a temperature range of -54°C to +66°C, it ensures long-term reliable operation in industrial environments. Its design facilitates the installation, maintenance, and safe operation of power plants, industrial automation, and multi-machine parallel control systems.
