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 competitors 48V alternators, having a direct impact on the alternators lifespan.

Good toy for dogs
Size: Large Size 3, Color: White-Blue
Bought this for our husky. Thought it would be bigger but it’s a good size for her. She has not managed to tear it apart after having it for a few months.

Puppy proof!
Size: Large Size 3, Color: White-Blue
Purchased the blue ball. Puppy loves to carry and shake the ball with the strapes in her mouth. Lots of bite marks but hasnt popped it. We bought 2. She plays in her fenced in yard with them. Fun to throw and kick around.
