Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on the alternator lifespan.

They actually last!!!!
Size: 9.5 inch (Pack of 1)
My pitties are CHEWERS!! Most toys don’t last more than a few minutes, if they’re decent then maybe a day or two but these sticks are still going strong!! I ended up getting more cause I was so happy they actually lasted and you can’t beat the price!! My older male is a lot more into toys than my female but now we got a 4 month old bully pup who’s teething and tries to chew on everything!! They are slightly big for him as of right now but he can still easily chew on them and is growing fast -it’s more him trying to run with it in his mouth that is a little hard but they do have smaller options - I love that they can just chew on these for hours and hardly make a dent! If you have aggressive chewers these are a great buy!!

Amazing toy for large dog breeds!
Size: 9.5 inch (Pack of 1), Size: 9.5 inch (Pack of 1)
My puppy Rottweiler loves this toy! Withstands her heavy chewing and really seems to soothe her! It’s very loud against the floor. She struggled a bit at first with picking it up but now it’s no problem. Highly recommend for big dogs

My puppy's favorite stick, high quality
Size: 5.75 inch (Pack of 1)
Perfect quality chew toy for my dachshund puppy. She will spend several minutes everyday chewing on this. It is the perfect size for her small mouth and it doesn't show signs of wear like most sticks do.

Durable
Size: 5.75 inch (Pack of 1), Size: 5.75 inch (Pack of 1)
Great buy would highly suggest for dogs that love to chew. I bout a large one for our 5 year old Husky and a medium one for our 11 week old puppy. Both are very intrigued by them and the puppy loves playing fetch with it. The only complaint I have is the size difference between the large and the small. I know measurements were given but the medium looks more like a very small stick. If you have a larger go with the Large size. Medium would really only work for smaller size dogs and pups
