ARCO Marine Zeus 24V 7kW N62 Alternator w/Clutch Pulley [4504]

Zeus 24V 7kW N62 Alternator with Clutch Pulley

The ARCO Zeus 24V 7kW alternator is a powerhouse! It generates super - high amperage when cruising or at higher RPMs. At just under 3,000 alternator RPM, it continuously pumps out over 3kW (109 Amps), and at under 6,000 RPM, it reaches almost 6kW (218 Amps). In practical terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio gets over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio hits over 6kW!

This alternator kicks in for cruising or at mid - to - higher RPMs. It runs cooler and offers more power than those old, bulky designs. The new era of 24V performance is here!

Competitors' 24V alternators use a 12V rotor and field current, which is less efficient and limits output at all RPMs. ARCO uses a native 24V rotor and field current, making our 24V alternator run cooler and last longer.

Features:

• Designed for high - energy production.
• Great for marine, RV, military, and commercial use.
• Charges large battery banks quickly.
• Cool operating temperatures for better performance: heat - shedding coatings, rectifier on the housing exterior, and dual cooling fans.
• Uses OEM components.
• Performs well at idle speeds.
• Creates extra power with your engine, reducing the need for a generator.
• With E - Coat/Cerakote, it keeps the high - amp alternator cool for steady amperage output.
• For top performance or lithium battery charging, pair it with the ARCO Zeus Bluetooth Alternator Regulator.
• SAE J1171 Certified and proudly made in the U.S.A.

Using the ARCO Zeus 24V 7kW alternator is easy. First, make sure it's properly mounted according to the specifications for your vehicle, whether it's a marine diesel engine or a Mercedes Sprinter. The alternator will start working once your engine reaches the cut - in RPM of 1,962. It'll charge your battery banks during cruising or at mid - to - higher RPMs. For the best performance, especially when charging lithium batteries, use the ARCO Zeus Bluetooth Alternator Regulator. When it comes to maintenance, keep an eye on the operating temperature. It can operate up to 100°C / 212°F, but try to avoid extended periods at high temperatures. Check the components regularly, like the pulley, diodes, and battery post. Make sure the coatings are intact as they help with heat shedding. Also, ensure that the external regulation is working properly. If you notice any unusual noises or a drop in performance, it's a good idea to have it checked out. And remember, this alternator is proudly made in the U.S.A. and is SAE J1171 Certified, so you can trust its quality.
