This module is essential for automated frequency matching and phase locking, allowing for the reliable paralleling of generators to a common electrical bus. By automating these critical synchronization steps, the 9905-003 prevents common manual errors and protects mechanical drive trains from the stress of out-of-phase coupling. It is widely deployed in demanding applications, including marine power systems, mining microgrids, and peak-shaving utility plants.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomated Synchronization:\u003c\/strong\u003e Manages phase and frequency matching to ensure seamless breaker closure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Sharing Capability:\u003c\/strong\u003e Maintains proportional distribution of electrical demand across multiple generator units based on rated capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Sensitivity Control:\u003c\/strong\u003e Utilizes a responsive analog control loop for real-time monitoring of bus and generator voltage relationships.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Design:\u003c\/strong\u003e Engineered for installation in harsh industrial environments, featuring integrated vibration resistance and EMI shielding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Configuration:\u003c\/strong\u003e Supports selectable 115 VAC or 230 VAC input voltages to accommodate diverse power infrastructure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e9905-003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eWoodward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSPM-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e115 VAC or 230 VAC (selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003e50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Offset Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 5 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Ensure the unit is securely chassis-mounted within a control enclosure.
