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.

Competitors 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 competitors 24V alternators, having a direct impact on the alternator lifespan.

waste of money, not indestructible, poor quality mess
Color: Grey Elephant
not at all indestructible. i have an average chewer dog at best, the guts were all over the floor in less than a minute and the squeaky part was out in less than four. felt like an insanely misleading advertisement. "for aggressive chewers, indestructible." massive waste of money. def don't recommend. Cheap quality, I think a lap dog would have ripped it apart in no time at all as well.

Good chew tolerance and the pup loves it
Color: Yellow Lion
Our dog (20 lb Lassapoo) has had the lion toy since Christmas morning; so far so good. She loves it. Would suggest one of the alternative variants instead of the lion. The long mane hairs are easily pulled off and could be swallowed.
