Zeus 24V 4kW Low Turn On (LTO) Vortec 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.

fun toy
Color: Orange
Very cute toy .My dog loves it. He is hard on toys and loves playing pully. So far it is holding up really well. It is a good size for medium to large dogs. I think if you have a small breed it may be to large. The color is a vivid orange and white. I really think your dog will love it.

Will buy again
Color: Orange, Color: Orange
This was one of the first toys I got my dog and he LOVED IT. I sadly had to throw it away because he peed on it but this is something I will definitely repurchase. Perfect for tug of war and playing fetch. Definitely not indestructible as he did rip it a little but it took him a LONG time to do that

Remains a favorite
Color: Orange
This toy was perfect for my pup who's a big biter and most toys will last about 2-3 days. The material on this toy is very durable and remains the favorite with the crinkling sound.
