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.

Leather purse
Color: Coffee
The purse is not to big or small. I like being able to readily carry it different was easily. The exterior back zip pocket is great for carrying a little cash and my most frequently used credit cards. My only complaint would be I'd like the interior open pockets to be a little deeper. I ordered the brown color. It looks and feels great.

Love this bag, wish it was even bigger!
Color: Sorrel
This is a nice squishy pebbled leather crossbody tote. I'm using it as a work bag BUT it won't fit a 16 inch laptop so if that's a consideration skip this one. It does fit a 10 inch iPad and Kindle, plus a compact umbrella, wallet, over ear headphones, full size body spray and lotion, big pack of gum, several lip products and dental floss, mini hand sanitizer, small brush, pens and a notebook... So basically my whole life fits in it aside from my laptop. It smells like leather, and I love that. The brown color has lots of variations so it looks like it has a patina already. I sprayed it with Apple Garde for waterproofing and it didn't affect the feel or color of the bag at all. This bag is really pretty and I get compliments on it daily. The zipper seems sturdy and never catches or gets stuck. It molds itself to my body like a softer leather should and I would say that it's absolutely worth the price. The strap is wide, sturdy, and comfortable too. There are multiple pockets on one inner side, a zippered middle compartment, and a zippered side compartment on the inside as well, along with an outer pocket so there's plenty of organization without having to buy an insert. I wish they had this available in an even bigger size to fit a standard laptop!

Expectations not met re. bag!
Color: Navy Blue
The seller was fantastic, as he/she accepted my return and refunded me immediately. Seller gets 5 stars. Even thou this bag is a stunning Navy Blue, BEAUTIFUL stitching, beautiful zippers and liner, wrapped professionally with TLC, I could not stand the very strong smell. I don't know if the smell was due to the navy blue color/dye or not. I can't even describe the smell... besides that it's not leather. I was gifted the same bag in "light brown" and that bag smells like leather; it's like you are in Rome shopping for the real thing! I love that bag as I can wear it crossbody, shoulder or hand held. Unfortunately, it too small for me. So I thought, if I am buying bigger, let's do the dark blue. Was I wrong. I really had high expectations for this bag. :0(

Love it
Color: Sorrel
So thought I would give this purse a try. Never bought anything like this on Amazon. My much much more expensive designer brand had to be replaced. I really like this purse. It’s the perfect size and very nicely made
