This alternator continuously generates over 3kW (55 Amps)at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!\u003c\/p\u003e\u003cp\u003eInstead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitors 48V alternators, having a direct impact on the alternators lifespan.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEngineered for high energy production.\u003c\/li\u003e\n\u003cli\u003eSuitable for marine, RV, military, and commercial applications.\u003c\/li\u003e\n\u003cli\u003eRapidly charges large battery banks.\u003c\/li\u003e\n\u003cli\u003eCoolest operating temperatures for increased performance:\u003c\/li\u003e\n\u003cli\u003eHeat shedding coatings\u003c\/li\u003e\n\u003cli\u003eRectifier located on housing exterior\u003c\/li\u003e\n\u003cli\u003eDual cooling fans\u003c\/li\u003e\n\u003cli\u003eOEM components\u003c\/li\u003e\n\u003cli\u003eOptimized for performance at idle speeds.\u003c\/li\u003e\n\u003cli\u003eReduces the need for a generator by creating additional power with your engine.\u003c\/li\u003e\n\u003cli\u003eUnleash peak performance with E-Coat\/Cerakote, keeping the high amp alternator cooler for sustained amperage output.\u003c\/li\u003e\n\u003cli\u003eUse the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging.\u003c\/li\u003e\n\u003cli\u003eSAE J1171 Certified.\u003c\/li\u003e\n\u003cli\u003eProudly made in the U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVoltage - 48v\u003c\/li\u003e\n\u003cli\u003eField Type - P\u003c\/li\u003e\n\u003cli\u003eRotor Poles - 16\u003c\/li\u003e\n\u003cli\u003eStator Size - 138mm\u003c\/li\u003e\n\u003cli\u003eFrame Size - Large\u003c\/li\u003e\n\u003cli\u003eWeight - 15.89lbs\/7.2kg\u003c\/li\u003e\n\u003cli\u003eRegulation - External Only\u003c\/li\u003e\n\u003cli\u003eFinish - (Black) E-coating\u003c\/li\u003e\n\u003cli\u003eCut-In RPM - 1,920 Alternator RPM\u003c\/li\u003e\n\u003cli\u003eMaximum Alt RPM - 19,000\u003c\/li\u003e\n\u003cli\u003eBattery Post - M8 Thread Post, Side Mount\u003c\/li\u003e\n\u003cli\u003eStandard Pulley - 49K6 (6-groove, 49mm)\u003c\/li\u003e\n\u003cli\u003ePulley Mount - 17mm diameter shaft, 25mm long, threaded M17 x 1.5\u003c\/li\u003e\n\u003cli\u003ePulley Hardware - M17 x 1.5 x 24mm nut, w\/ 18mm ID x 29mm OD washer (Included)\u003c\/li\u003e\n\u003cli\u003eDiodes - 6 positive, 6 negative, 80A Rated, Avalanche\u003c\/li\u003e\n\u003cli\u003eMax Output (Cold, 9,000 RPM) at 53.5v - 180 Amps - 9,360 Watts  14.8 kW PTO\u003c\/li\u003e\n\u003cli\u003eSustained Cruising Output (Hot, 6,000 RPM) at 53.5v - 138 Amps - 7,383 Watts  10.5 kW PTO\u003c\/li\u003e\n\u003cli\u003eSustained Idle Output (Hot, 2,500 RPM) at 53.5v - 78 Amps 4,173 Watts  6kW PTO\u003c\/li\u003e\n\u003cli\u003eMax Continuous Operating Temperature - 100C \/ 212F\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eMounting Application:\u003c\/strong\u003e\u003c\/p\u003e\u003cul style='box-sizing: border-box; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-variant-alternates: inherit; font-variant-position: inherit; font-variant-emoji: inherit; font-weight: 400; font-stretch: inherit; font-size: 14px; line-height: inherit; font-family: -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, \"Helvetica Neue\", Arial, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\"; font-optical-sizing: inherit; font-size-adjust: inherit; font-kerning: inherit; font-feature-settings: inherit; font-variation-settings: inherit; margin: 0px; padding: 0px; vertical-align: baseline; list-style: inside disc; color: rgb(33, 37, 41); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'\u003e\u003cli style=\"box-sizing: border-box; border: 0px; font: inherit; margin: 15px 0px; padding: 0px; vertical-align: baseline; display: list-item; list-style-type: disc;\"\u003eReplaces most Volvo Penta alternators using a 4 J180 saddle-style mount.
