Zeus A8000-48V 8kW J180 4" 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.

Fantastic variety of doggie toys perfect for our little fur baby!!!
Color: 25 Pack (Value-Toys)
Fantastic for smaller dogs, our little chi-mix loves all of the toys, there's such a great variety and he's having so much fun chewing them and playing fetch with them. Even comes with many extra rolls of waste bags which is awesome. Highly recommended for the value and amount you receive!

SMALL DOGS ONLY!!!!
Color: 25 Pack (Value-Toys)
Every one of these toys are made for very small dogs. 🤣 They're almost too small for my 8 wk old border collies. Im still not upset at the order though as the pups will all be rehomed after this weekend. Was just bummed that every single one was made for SMALL DOGS. Am super happy with how fast shipping was.

Nice dog toys
Color: 25 Pack (Value-Toys)
Nice toys, but no match for my 2 year old female pitbull. Most toys she shreds. Even some that are supposed to be indestructible. Some of these lasted for a while.

Great and solid chew toy for those "eager" chewers!
Color: Blue Shark, Size: Medium, Color: Blue Shark, Size: Medium
This is a winner! Especially if your dog is an aggressive chewer. My dog is a 30 lb on the outside but on the inside is a 200 lb tiger/bear who likes to gnaw/destroy everything. I only wish I were joking. We've had this little toy for however long now and she goes to town on it and I don't have to worry like I do with other toys. Because no pieces are falling off or breaking off and she's a happy camper. And I'm a happy camper because I'm not all up in her gnawing business. As you see in the picture this is the perfect size for her. I think she is a mini aussiedoodle but she's approximately 30 to 33 lb of pure energy, love, sloppy kisses, and aggressive chewing. Best toy has its me money by not having to replace more shoes and chargers of all sizes. I think it's kind of cute and she is very protective of it. As I was taking pictures to post, she came to me, got it, trotted off, and you see the end results: her with the toy, protectively holding on to it. She loves this thing and I'm about to order another one just to have just in case. I will mention it is heavy for its size. But unless you want to knock somebody out, I wouldn't recommend throwing it. At all. I don't think any dog smaller than her could carry it around and I don't have a scale to weigh it but this is the perfect size for her. This truly was the best chew toy I have gotten her in about a year, and I am not exaggerating. We are huge fans!!!

good toy for heavy chewers
Color: Blue Shark, Size: Medium
My dog loves this toy. It is tough and has a nice squeak. The only thing that bothers me a bit (it doesn't bother the dog) is the plastic tail gets rough with the chewing.
