Zeus 24V 7kW 3.15 Alternator with Isolated Ground (Common Rail) & Zeus High-Energy Alternator Regulator

Zeus 24V 7kW 3.15 Alternator with Isolated Ground (Common Rail)

The ARCO Zeus 24V 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!

The ARCO Zeus 24V 7kW alternator turns on for cruising or at mid to higher 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 competitors’ 24V alternators, having a direct impact on the alternator's 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 idle 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

Zeus High-Energy Alternator Regulator

ARCO’s Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technician’s configurations. 

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternator’s power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternator’s performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus’ ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

Zeus A8000-48V 8kW N62 Alternator with Clutch Pulley & Zeus High-Energy Alternator Regulator

Zeus A8000-48V 8kW N62 Alternator with Clutch Pulley

The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps)at  2,500 RPM and almost 6kW (111 Amps) at 4,000 RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!

Instead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors, which are less efficient and limit output at all RPMs. In this scenario, your external smart regulator must drastically reduce the field by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitors’ 48V alternators, having a direct impact on the alternator’s lifespan.

Features:

• Engineered for high energy production.
• Suitable for marine, RV, military, and commercial applications.
• Rapidly charges large battery banks.

Zeus A275L N62 Alternator with Clutch Pulley & Terminal Block

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.
• It is optimized for performance at idle speeds.
• Reduces the need for a generator by creating additional power with your engine.

Zeus High-Energy Alternator Regulator

ARCO’s Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information allows you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technician’s configurations. 

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternator’s power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternator’s performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus’ ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.
