This module facilitates the seamless paralleling of power units to a common bus, ensuring stable grid synchronization. It is widely employed in peak-shaving power plants, marine propulsion systems, and mining site microgrids to eliminate manual synchronization errors. By maintaining precise control over engine speed and load distribution, the 9905-003 prevents high-stress mechanical coupling events, thereby extending equipment service life and reducing unscheduled maintenance downtime.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAutomated frequency matching and phase locking for generator paralleling.\u003c\/li\u003e\n\u003cli\u003eProportional load-sharing control across multiple active generators.\u003c\/li\u003e\n\u003cli\u003eHigh-sensitivity analog control loop for precise voltage and phase monitoring.\u003c\/li\u003e\n\u003cli\u003eRobust shielding and vibration damping for reliable operation in high-EMI industrial environments.\u003c\/li\u003e\n\u003cli\u003eSelectable input voltage ranges for versatile application compatibility.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIndustrial power generation and peak-shaving plants.\u003c\/li\u003e\n\u003cli\u003eMarine propulsion and auxiliary power management.\u003c\/li\u003e\n\u003cli\u003eMining site microgrids and distributed energy systems.\u003c\/li\u003e\n\u003cli\u003eStandby power systems requiring automatic synchronization.\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\u003eBrand\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\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eLoad Sharing Speed Controller\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 or 60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Offset Accuracy\u003c\/td\u003e\n\u003ctd\u003eLess than 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\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the unit is mounted in a chassis with adequate vibration damping to protect internal components.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for all control and sensing inputs to minimize the impact of high-EMI environments typical of engine rooms.\u003c\/li\u003e\n\u003cli\u003eVerify that the voltage selection jumpers or switches are configured correctly for your specific supply voltage (115 VAC or 230 VAC) before applying power.\u003c\/li\u003e\n\u003cli\u003eAlways isolate power to the controller before performing any wiring changes or maintenance.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the module chassis to the main control panel ground bus to maintain signal integrity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 9905-003?\u003c\/h3\u003e\u003cp\u003eThe 9905-003 acts as a synchronizer to match the frequency and phase of a generator to a bus, and subsequently as a load-sharing controller to distribute electrical demand proportionally across multiple generators.\u003c\/p\u003e\u003ch3\u003eCan this unit operate on both 50 Hz and 60 Hz systems?\u003c\/h3\u003e\u003cp\u003eYes, the Woodward SPM-A 9905-003 is designed to support both 50 Hz and 60 Hz power systems.\u003c\/p\u003e\u003ch3\u003eWhat environmental conditions is this controller rated for?\u003c\/h3\u003e\u003cp\u003eThe module is designed for industrial environments and is rated for an operating temperature range of -40 to +70 deg C.\u003c\/p\u003e","brand":"Woodward","offers":[{"title":"Default Title","offer_id":50644194197756,"sku":"9905-003","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_df2db105-0eae-465a-99de-71a805fa4c2b.jpg?v=1784960878","url":"https:\/\/www.electronicplc.com\/ar\/products\/9905-003-woodward-spm-a-synchronizer-load-sharing-speed-controller","provider":"Electronic PLC","version":"1.0","type":"link"}
