Zeus A275L Vortec Alternator with Regulator

The highest power output alternator in its size/class. 

Features:

• Engineered for High Energy Production.
• Suitable for Marine, RV, Military, and Commercial applications.
• Rapidly charges large battery banks.
• Coolest operating temperatures for increased performance. 
• Runs 8 - 20% cooler than incumbent alternators due to: Heat shedding coatings, Rectifier located on housing exterior, Dual cooling fans, and OEM Components.

Zeus 24V 4kW Low Turn On (LTO) 1"-2" Single Foot Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. 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)!

The 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.

Competitor’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 onthe  alternator lifespan.

Features:

• Engineered for high energy production.
• Suitable for marine, RV, military, and commercial applications.
• Rapidly charges large battery banks.
• Coolest operating temperatures for increased performance:
• Heat shedding coatings
• Rectifier located on housing exterior
• Dual cooling fans
• OEM components
• Optimized for performance at cruising speeds.
• Reduces the need for a generator by creating additional power with your engine.
• Unleash peak performance with E-Coat/Cerakote, keeping the high amp alternator cooler for sustained amperage output.
• Use the ARCO Zeus Bluetooth Alternator Regulator for maximum performance or lithium battery charging.
• SAE J1171 Certified.
• Proudly made in the U.S.A.

Technical Specifications:

• Voltage - 24v
• Field Type - P
• Rotor Poles - 16
• Stator Size - 138mm
• Frame Size - Large
• Weight - 15.89lbs/7.2kg
• Regulation - External Only
• Finish - (Black) E-coating
• Cut-In RPM - 1,072 Alternator RPM
• Maximum Alt RPM - 19,000
• Battery Post - M8 Thread Post, Side Mount
• Standard Pulley - 49K6 (6-groove, 49mm)
