Zeus 24V 4kW Low Turn On (LTO) J180 4" 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 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 competitors’ 24V alternators, having a direct impact on the alternator's lifespan.

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.

Features:

  • 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

Durable tug toy that our pitbull absolutely loves
As soon as I pulled this toy out, our pitty saw it and immediately wanted to play. Tug is her absolute favorite thing to do, and she is crazy about this one. She constantly looks for anyone willing to play with her. That makes me really appreciate the grip loops because they keep our hands comfortable during the tug sessions making it easy to play with her. Our house is also run by an 8 lb Chihuahua who is definitely the alpha. Believe it or not, our big pitty is scared of the little dog and just lets her steal the toy away. She just patiently waits and grabs it back the second the Chihuahua loses interest. The size is great as both dogs can get good bites on it for secure hold. We have had it for a month now, and it is holding up perfectly without any real damage. Best of all, our she still enjoys it just as much as she did on day one. I really like that it is made in the USA from BPA and latex-free materials. It cleans up easily in the dishwasher and even floats when we take it down to the ponds. --- For anyone interested, the exact product I purchased was listed as: Wagalicious, Tuggfinity, Lime The ASIN for the version I received was:

Fun Toy for Large Dogs, but Hard to Grab from Flat Surfaces
I gave this to a large dog to see how it would hold up during play. He really enjoys it and stays engaged with it, especially during active play sessions. The material feels durable enough to handle a bigger dog’s strength. It’s bright and easy to spot, which helps when playing outdoors. It’s clearly designed for interactive play. One thing I noticed is that it can be a little difficult for him to pick up off the ground. The shape doesn’t give much to grab onto when it’s lying flat. Once he gets it, he enjoys it, but getting started can take a second. It’s still a fun toy, just something to keep in mind. Works best when tossed or handed to them.

An absolute powerhouse for heavy chewers—survived the "same-day" test!
Finding a toy that can survive a large dog is usually an expensive game of trial and error. More often than not, new toys end up destroyed in the exact same day we buy them. However, the Wagalicious Tuggfinity Lime toy has completely defied expectations. This large, lime green tug toy is built like a tank. It is the perfect size for larger breeds and has actually held up incredibly well to intense tugging and heavy chewing sessions. Instead of shredding into pieces within hours, it’s still going strong. The best part is the price point. At around $15, the value is absolutely awesome. Usually, you have to pay a massive premium for "indestructible" style dog toys, but this one gives you top-tier durability without breaking the bank. If you have a big dog that demolishes everything, this is a must-have.

Dad approved
I bought this because my dogs do not want “gentle play.” They want something they can really grab, shake, and try to win. This has been a great tug toy for that. The material feels thick, the stitching has held up, and it has enough grip that I can keep control without it slipping. It is also easy to rinse off after backyard dirt and dog drool. This is the kind of toy that actually gets used instead of ending up ignored in the corner.
