This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!\u003c\/p\u003e\u003cp\u003eThe ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.\u003c\/p\u003e\u003cp\u003eCompetitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on the alternator lifespan.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\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 cruising 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\u003eFor maximum performance or lithium battery charging, use the ARCO Zeus Bluetooth Alternator Regulator.\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\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width: 100%;
