Zeus 24V 7kW J180 4" Alternator with Isolated Ground & Zeus High-Energy Alternator Regulator

Zeus 24V 7kW J180 4" Alternator with Isolated Ground

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.

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.

  • Secure Bluetooth connection
  • Harnesses, Thermistors, and NMEA 2000 kit included
  • Monitors the state of charge
  • Can turn your engine into a dedicated generator with generator mode
  • Pre-set battery libraries

1/2 size too big!!!
Size: 7 Wide, Color: Black Leather
My entire adult life I have been a size 7, regardless of brand, I should have known right away when I tried them on, but I was so excited to go out to dinner in them that I ignored the obvious, they are for sure a 1/2 size too large for me. Thank God for the ankle strap, otherwise they would have had me a@@ over tea kettle the first time I got out of the car. I feel like I'm a kid, wearing my mom's shoes. I shouldn't have worn them out. I should have gotten a smaller size. I still might. They're super cute and comfortable. But SIZE DOWN. Especially if you ordered wide. This is now the second pair in a week I purchased from Naturalizer, and apparently they just make shoes that are 1/2 a size bigger than everyone else. I managed to return the other pair.

Cute great size got a lot of compliments
Color: Obsidian Black
Loved this. Got it on sale dor 34.99 and worth it it seems like a good staple for events / outtings. Even daily use probably, but I got it for a wedding event.weekend and got so many compliments! Good closure zipper had no issues. I like the material doesn’t look or feel cheap, good color. (I got black) but saw someone at event with gold one and also adorable!!! Storage is huge for me - it easily fit my phone, a couple of pads and tampons, small hand sanitizer, small aquaphor with room! I also had sunglasses in there at one point and surprisingly zipped fine with all of that. Overall convenient for storage, aesthetically pleasing, good material-quality. Cons: the chain strap bothered my neck a little bit after wearing it but that’s a me problem. Not the purse/way it was made. But something to consider.

Cute and versatile clutch purse
Color: Apricot Beige
Very nicely made, can use as a clutch, a shoulder or the chain can be doubled and makes a great little purse, roomy and closes with a zipper so you don't lose things like I do. Will probably get more in different colors, soft leathery material.
