Its robust design ensures rapid charging of large battery banks, supporting extended operation and reliability. The alternator features advanced heat shedding coatings and dual cooling fans, allowing it to run 8 to 20% cooler than comparable models, which enhances performance and prolongs service life. Additionally, the exterior-mounted rectifier and high-quality OEM components contribute to consistent operation and durability.\u003c\/p\u003e\u003cp\u003eThis alternator is optimized for performance at idle speeds, helping reduce the need for a separate generator by generating additional power directly from the engine. The use of E-Coat or Cerakote advanced coatings further improves heat absorption, enabling the unit to sustain higher amperage levels over longer periods. For optimal performance, especially with lithium batteries or maximum output demands, pairing it with an ARCO Zeus Bluetooth alternator regulator is recommended. Certified according to SAE J1171 standards and proudly manufactured in the USA, this alternator offers dependable power with innovative thermal management.\u003c\/p\u003e\u003cp\u003eTechnical features include a 12-volt system with a 16-pole rotor, a 130mm stator size, and a compact frame weighing approximately 12 pounds. It provides a standard output voltage of 14.1 volts and features external regulation for precise voltage control. The unit's maximum cold RPM is 9,000, with a peak RPM capacity of 19,000. It comes with a side-mount M8 threaded battery post and a standard 49mm, 6-groove pulley, including hardware for installation. The internal diode assembly offers 50A avalanche-rated diodes, supporting high current loads. Its cooling and heat management capabilities, combined with a compact design, make it an excellent replacement for most small case alternators, including those used in Yanmar, Hitachi, Lucas, Mitsubishi, and similar models.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eEngineered for high energy production to support demanding power needs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for marine, RV, military, and commercial applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRapidly charges large battery banks for extended operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRuns 8-20% cooler thanks to heat shedding coatings, exterior-mounted rectifier, and dual cooling fans\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUses OEM components for durability and reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized for performance at idle speeds, reducing the need for a generator\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdvanced E-Coat\/Cerakote coating minimizes heat absorption, supporting higher amperage output\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with ARCO Zeus Bluetooth alternator regulator for maximum performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSAE J1171 certified for quality and safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for easy mounting on most small case styles using a 3.15-inch J-180 saddle mount\u003c\/li\u003e\u003c\/ul\u003e","brand":"ARCO Marine","offers":[{"title":"Default Title","offer_id":44431848046634,"sku":"107331","price":767.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/107331XL.jpg?v=1780876745","url":"https:\/\/atticusgoods.com\/products\/arco-marine-zeus-a225s-j-180-3-15-inch-alternator-with-terminal-block-for-marine-and-commercial-use","provider":"Atticus Goods","version":"1.0","type":"link"}
