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

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.

Sleepy time.
These melatonin pills work well at easing my anxieto, late at night. I can then proceed to swiftly fall asleep. The good thing is that it just takes one pill, and that alone packs a decent punch. Satisfied with my purchase of this product, thus far.

Works Fast! Finally Getting a Great Night's Sleep.
If you struggle with insomnia like Ihave for years, try these, they work incredibly well and have completely fixed my sleep routine! ​I usually take one about 20 to 30 minutes before I want to go to bed, and like clockwork, a gentle relaxation washes over me and I drift right off to sleep. Great fast shipping.. thanks!!

Everyone is different but worked for me!
These work for me! They don't have a taste, pill size isn't too big and definitely a great price for what you get. Puts me to sleep within 30-60 minutes. Everyone is different, but they definitely worked for me!

Smallish pills!
Great way to take melatonin. The pills are small enough so you don't choke and they work pretty fast. I've no idea about the taste, but it doesn't seem to have one. Sometimes I feel groggy in the morning but not overly so. Pretty good product.
