Delivering a nominal current of 140 A at a 12 V system voltage, it stands out from the standard Alpha series with its reduced footprint and optimized cooling thanks to an integrated dual-fan system, allowing it to operate up to 120 °C. For its drive, this alternator requires a 4.8 kW power take-off (PTO) on the engine.\u003c\/p\u003e\n\u003ch3\u003eIntegrated Alpha Pro III smart regulator\u003c\/h3\u003e\n\u003cp\u003eThis kit includes the advanced \u003cstrong\u003eAlpha Pro III\u003c\/strong\u003e charge regulator, turning this alternator into a three-stage smart charger (Bulk, Absorption, Float). Unlike standard regulators, it automatically compensates the charging voltage based on temperature (-30 mV\/°C at 12 V) to effectively protect battery banks (lead, gel, AGM, or lithium-ion). Fully compatible with the MasterBus communication network via its two RJ-45 ports, it provides complete system monitoring, including alternator temperature, excitation current, and voltage alarms, facilitating integration with other equipment such as the MasterShunt.\u003c\/p\u003e\n\u003ch3\u003eReady for installation\u003c\/h3\u003e\n\u003cp\u003eThe Alpha Compact 14\/140 VP alternator is supplied ready-to-use with a standard pulley for 8-rib multi-groove belt (48.1 mm diameter). The kit also includes a hydrocarbon-resistant wiring harness, a battery temperature sensor, and robust connections, including an M8 stud for the positive terminal. While not isolated by default, an insulating bushing kit is available as an option for systems requiring strict galvanic isolation.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":53723875410260,"sku":"46614142","price":2397.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main-square_643623ab-fed6-4f4b-a2c3-97445cd0887b.jpg?v=1778053117","url":"https:\/\/skysat.fr\/en\/products\/mastervolt-alpha-compact-14-140-vp-alpha-pro-iii-12v","provider":"Skysat","version":"1.0","type":"link"}
