Rated for 230 V, 60 Hz operations, this unit automates the critical process of matching generator frequency, phase angle, and voltage before the circuit breaker closes. By providing automated control, the 9905-002N significantly reduces the risk of out-of-phase closure, protecting prime movers and electrical switchgear from severe mechanical and electrical transients.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInternal phase-lock loop (PLL) circuitry for real-time phase angle monitoring.\u003c\/li\u003e\n\u003cli\u003eAdjustable setpoints for phase window and dwell time to accommodate varying load dynamics.\u003c\/li\u003e\n\u003cli\u003eProportional bias output signal for seamless integration with engine governor systems.\u003c\/li\u003e\n\u003cli\u003eRuggedized construction designed for reliable operation in high-vibration industrial environments.\u003c\/li\u003e\n\u003cli\u003eHigh electromagnetic interference (EMI) immunity for stable performance in power generation facilities.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThis synchronizer is widely deployed in mission-critical power management environments, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIndustrial power generation and cogeneration plants.\u003c\/li\u003e\n\u003cli\u003eStandby and emergency power systems for refineries and chemical processing facilities.\u003c\/li\u003e\n\u003cli\u003eMicrogrid management for mining operations and remote sites.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e9905-002N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eWoodward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Type\u003c\/td\u003e\n\u003ctd\u003eSPMA Synchronizer Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e230 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e10 W\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\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-55 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.88 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the system power is completely disconnected before installing or removing the module.\u003c\/li\u003e\n\u003cli\u003eMount in a clean, dry, and vibration-dampened control panel enclosure.\u003c\/li\u003e\n\u003cli\u003eMaintain adequate clearance around the unit for proper thermal dissipation.\u003c\/li\u003e\n\u003cli\u003eUse shielded, twisted-pair cabling for all analog inputs to minimize noise pickup.\u003c\/li\u003e\n\u003cli\u003eVerify that the ground connection is secure to maintain EMI protection integrity.\u003c\/li\u003e\n\u003cli\u003eConfirm that the phase-matching logic settings align with site-specific generator and bus requirements before commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary function of the 9905-002N?\u003c\/strong\u003e\u003cbr\u003eThe 9905-002N acts as an automated synchronizer that manages the frequency, voltage, and phase matching of a generator to a bus, ensuring safe and stable circuit breaker closure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this module suitable for high-vibration environments?\u003c\/strong\u003e\u003cbr\u003eYes, the 9905-002N is built with a ruggedized industrial design capable of maintaining logic stability in harsh engine room conditions.\u003c\/p\u003e","brand":"Woodward","offers":[{"title":"Default Title","offer_id":44692948418648,"sku":"9905-002N","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/wm_1_c9075b71-5d87-4314-9022-d0c5e27a6d10.jpg?v=1788284681","url":"https:\/\/www.industriaxplc.com\/ar\/products\/woodward-9905-002n-spma-synchronizer-control","provider":"IndustriaX Limited","version":"1.0","type":"link"}
