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.

Gentle soap, great for hands and body!
I love how gentle this oatmeal soap is. It’s perfect for sensitive skin and doesn’t irritate my hands even when they are rough. I keep one at my sink and one in the shower. The natural scent is lovely and not overpowering. A must-buy for those looking for a mild cleanser!

Itchy, red skin BE GONE!
My 94 year old father has recently had a terrible resurfacing of his psoriasis with red, itchy, flaky sores all over his body! It's been so bad that he can't even sleep at night. My heart has been aching for him BUT he is finally getting some relief from this amazing soap!! I just saw him yesterday and, compared to two weeks ago, the redness and itching has lessened considerably. Plus, he loves the way it smells! What a true JOY to know he is on the mend, in part because of this product. I am about to purchase another bar for my sister who suffers the with the same issue. THANK YOU fo making a product that actually does what it claims to do!!!!!!

Great Product
I’ve been using this all-natural eczema soap for the past few weeks, and I’m genuinely impressed by the results. As someone who has struggled with eczema flare-ups for years, I’ve tried countless products, but this soap stands out. First off, the ingredients are truly natural—no harsh chemicals, fragrances, or preservatives. The soap is made with soothing, skin-friendly components like coconut oil, shea butter, and chamomile extract. It lathers up nicely, creating a gentle, creamy foam that feels luxurious on the skin. What really stands out is how gentle it is on my sensitive skin. Unlike many other soaps I’ve tried, this one doesn’t dry out or irritate my eczema patches. In fact, it has a calming effect and seems to reduce redness and itching after just a few uses. I’ve noticed that my skin feels softer and more hydrated, which has helped prevent flare-ups. The scent is mild and pleasant—not overpowering, but just enough to give you a fresh, clean feeling without triggering any sensitivities. Overall, I’m thrilled with this eczema soap. It’s not only effective at soothing and moisturizing my skin, but it’s also a relief to know that I’m using something that’s completely natural and safe. If you suffer from eczema or other skin sensitivities, I highly recommend giving this soap a try. It’s definitely become a staple in my daily skincare routine.
