Zeus A8000-48V 8kW 3.15 Alternator with Isolated Ground (Common Rail)

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.

The cutest earrings I've seen in a while.
Color: 07.Jul, Color: 07.Jul
We were so happy to get these beautiful and cute silver stud butterfly earrings. The colored CZ let us customize the color to personal preference, which let us pick the perfect option. I really like the silver setting. It is quite well done, and looks far more premium and higher quality than the low price would lead you to believe. One thing I really like about these earrings is the size. These ended up being the perfect size, and made for a very cute look. I honestly think these might become the new daily-wear earrings. They look fantastic. Included are the earrings, a pouch, and two styles of backing. Both backing options were very easy to use, and held the earrings securely. The stud was of good quality, and plated in silver along the whole stud. It is difficult to tell for sure, but this seems like the plating was well done. I think these should hold up well over time. The studs are a little on the long side, but no discomfort was had wearing them. Honestly, I thought it made it easier to put them on. Though, they might not be a good one to wear sleeping or something. It is easy to recommend these super cute earrings. They will be worn frequently, come in a variety of colors, and are well made. I am very happy with them.

These little butterfly Earrings are the perfect touch of personality for your ears. I got these for a friend's birthday and she's worn them every day since. When I picked these up, they were advertised as sterling silver which was a necessity for her ears. She hasnt had any issues and she hasn't had to take them out at all. The clasps are your average butterfly backing. And she did note that the back came off during sleep one night but it could be she is a hard sleeper. Other than that, they are secure. They are larger studs. Not awful large or gaudy. But people have noticed and complimented on them. They add that perfect touch of whimsy without exclaiming give me attention. Perfect to dress up or down and birthstones match anything after all!

Cute little butterflies!
Color: 10.Oct(Pink Tourmaline), Color: 10.Oct(Pink Tourmaline)
I got these for my daughter who just recently got her ears pierced for the first time. Since she is so young, I decided to try them first to see how well they handle. First, I was very impressed that they included plastic and metal backs. There’s also a nice little baggie to put the earrings in when they’re not in use. Second, my ears are very sensitive, which was a concern with wearing these, but after a few hours, they seemed to be fine still. Usually, after a few hours, I have to take earrings out. I could have worn these for longer and been OK. Last they are super cute! They match the description and color perfectly! I was very impressed. I could definitely see myself buying another pair. The earrings were also very good size not too big and not too small. Perfect for adult or child.

These really are so cute--the purple color of the butterfly really stands out and when I'm wearing them, I can't even tell that I have them on.
