Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground (Common Rail)

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

We call him Armie! Dog loves it.
Color: Blue, Size: 14 IN
The dog loves it! Routinely carries it around squeaking all the way. The squeak is more like a quack and makes everyone giggle. It’s nice and big so a good match for our tall dog. Probably too big though for smaller dogs. Holding up well so far and that’s no mean feat given our pup’s destruction skills.

The chewability of this toy from 1-10 is a 10 all day 👍🏻
Color: Gray, Size: 8 IN
I have a Boston Terrier and he’s a serious extreme CHEWER! He loves this Hollypet Plush Dog Squeaky Toy Stuffed Armadillo! My doh gnaws on the tail, legs, the ears and the nose and all are still in tact. He’s had it for what I consider a long time. Usually he rips toys apart in the first day but this has been months! I throw this in the washing machine with his other stuffed animal toys simply because the ears, noses and tail get so stiff from chewing on them they need to be washed and they bounce right back just like new. Chewability from 1-10 is a 10 all day long! He plays with it a for a long while each time he uses it. Very active with his Armadillo and it’s so cute and the squeaker is just right, it’s not that loud screaming squeak. If he ever lost this or it got destroyed somehow? I’d buy him this all over again. Worth the money!

Fun dog toy, but not for heavy chewers
Color: Pink, Size: 14 IN
The armadillo is cute. My pittie, Sasha, was very excited to see it. She just had TPLO surgery on her left knee (she tore her ACL just before the 4th of July), and I wanted to get her something she could play with while she convalesces, that isn't a ball—she really likes to run and jump and chase the ball, but with her knee out of commission, I didn't want her to get depressed being trapped in her crate while she heals—with this toy, she was able to keep playing and not over excert herself and get more hurt. It quickly became her favorite toy; she chews it relentlessly and gets made when I take it from her (see below). It makes a funky squeak that's not a high-pitched squeak, like I thought it would be; it's more a low-pitched, lowing sound like a baby calf. One thing I would like to point out to other purchasers about what the description says: "Durable and Long Lasting - Made from premium soft materials, our cute plush dog toys can withstand rough play for indoor or outdoor and last for years to come. The textured surface also helps massage and soothe your dog's gums during playtime" This is a little misleading. It's a good texture and Sasha loved to play with it, but it wasn't very durable. It might be when compared to other chew toys, but not for my baby. She tore the nose off within 20 minutes of getting it. The next morning, she ripped off an ear, and I had to pull the stuffing out of the face so she wouldn't eat it while chewing away. She doesn't seem to mind, but I sure wish it had held up a little more. All-in-all, this was a good toy for a few days.

Best Balls Ever!!!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
