Zeus A8000-48V 8kW 1"-2" Single Foot Alternator with Isolated Ground

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 Alternator 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 is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce 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 competitor’s 48V alternators, having a direct impact on the alternator’s lifespan.

Highly entertained golden retriever!
Color: Green, Size: Large (3.0 in, Pack of 1), Color: Green, Size: Large (3.0 in, Pack of 1)
My golden retriever spends hours chasing this ball. Its erratic bounce pattern keeps him engaged and guessing where to chase the ball. It is durable and stands up to chewing well.

Great quality ball
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
The product is great no issues. It’s very durable. All of this brands products are strong and durable. The only reason I gave it a four star is I think my dogs prefer more the blue round balls. So that being said, I won’t buy these anymore, but they love the blue ones whether they’re the recycled or not. Great company!

Pups Love
Color: Green, Size: Medium (2-1/2 in, (Pack of 1)), Color: Green, Size: Medium (2-1/2 in, (Pack of 1))
As you can see from the photo, my pup absolutely loves it! It’s the perfect size for him and for reference he’s 25 pounds. It’s got a nice weight to it, but it’s soft enough to be able to throw and not worry about damaging the walls. We just started playing with it today, but it seems very durable.

Fun for the first day, but just get the round balls.
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
These balls do work, but they bouncy pretty much like a regular chuck it ball. They do NOT fit in the chuck it handheld ball launcher, which makes them a pain to throw. The green color also makes them somewhat challenging to find when the grass is long. That said, they do work as intended, and the dogs like them the same as all the other chuck it balls we own. As the person who had to throw them, my advice would be to just get the round balls that fit in the ball launcher. Durability: 9/10 they hood together better than the traditional balls without the hole (that crack down the seam over time). These have yet to crack despite the same wear and tear. Pros: durable, dogs like them, they do sink in water Cons: green color, hard to fit in handheld ball launcher
