Zeus A8000-48V 8kW Vortec 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.

VERY SMALL but otherwise perfect
Size: 9 Women/8 Men, Color: Black/White/Black
okay so one of my feet is slightly larger than the other, only like a quarter maybe half size, making shoe shopping difficult sometimes.. not often bc with sneakers and other closed toe shoes, it’s not usually a problem, it’s really only slides. anyway i’m a women’s 8.5 sometimes 9. if they only have whole sizes, 95% of the time I go with 9 and rarely an 8. i’ve never in my life bought shoes larger than a 9. it’s worth noting I recently bought two new adidas superstar sneakers in a 9 and I wear them when I want comfort bc they fit so well. that was maybe 6 months ago and I’m grown so they are not changing. I order the 9 (men’s 8/womens 9) and my left foot looks fine but the bigger foot is giving me pause. the shoes themselves were the exact length as my actual foot, leaving no room at the toe or heel, and my feet fit perfectly in the indentations of a foot.. but they just didn’t feel right. I walked around my carpet for a little bit and caught my toes hanging past the actual shoe and basically in mid air. At that moment I knew I needed to size up to a 10 which is crazy to me. The 10 got here today and fits much better, even though now it’s a little big on my smaller foot, but not enough to cause a problem. I’m just shocked i’m wearing a size 10 bc im 40 years old.. lol i’ve been buying shoes for quite some time and never once in my life did I need to size up to a 10. Surprisingly the 10s aren’t noticeably bigger all around, like in the actual strap that holds your feet. I love these slides, always have, I just don’t ever remember having to buy a 10. Personally, I think it’s because of the unisex sizing- men’s and women’s shoes are more than one size different. It’s closer to a size and a half. my parents had a shoe store for like 15 years so I promise you I know what I’m talking about. anyway I would absolutely recommend sizing up one whole size unless you know for a fact what size you wear in these specific shoes.
