It suits demanding marine, RV and commercial use where big lithium or lead-acid banks must be replenished quickly and often.\n\nARCO builds the A275L to run cool under sustained load. Heat-shedding Cerakote and E-coat finishes, an externally mounted rectifier and twin internal fans hold temperatures down so it keeps producing rather than derating. Its hot ratings are measured conservatively, after a full hour at 3,000 RPM beneath a plexiglass heat shield rather than in cool ambient air, so they reflect real engine-bay conditions.\n\nAs an externally regulated alternator it needs a dedicated controller such as the ARCO Zeus Bluetooth regulator, which is essential for safe lithium charging. This version uses a 3.15 inch dual-foot saddle mount with a rear-exit B+ post and case (standard) ground to drop straight onto post-2013 Yanmar common-rail engines. It is SAE J1171 certified and proudly made in the USA.","brand":"Arco","offers":[{"title":"Default Title","offer_id":56272823419220,"sku":"4020","price":1652.4,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/hme.sprechen.dev\/products\/arco-alternator-12v-275a-df315-dual-foot-3-15-side-battery-post-externally-regulated-standard-ground-49mm-k6-pulley-4020","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
