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.

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.

Nice quality casual shirt
Color: Print 02, Size: Large
I love this shirt! It was true to size, color and fit! I washed it in cold water and dried on permanent press. Put on a hanger immediately out of the dryer - no wrinkles! No shrinkage and no fade. Materials is light but is not see thru.

Very flattering
Color: Boho Print 03, Size: X-Large
Great shirts! I have a large bust, and they still look great! They're comfortable and don't cling, and they're machine wash and tumble dry low. This is my third one, and I may buy more.

Great shorts at a great price!
Fit Type: 7" Inseam, Size: X-Large, Color: Navy
Great shorts for a great price. Needed to replace a few pairs of my gym shorts but didn’t want to spend $40+ on a pair. Found these and decided to give them a try. Since getting my first pair I’ve bought 4 more in different colors and have been wearing them daily. They fit great, true to size. Love the zippered pockets so I’m keeping my phone & wallet secure. Extremely lightweight & fast drying. These work great for gym or just casual shorts. 10/10 would recommend.

Nice shorts, fabrics thin but a great fit.
Fit Type: 7" Inseam, Size: Large, Color: Light Green, Fit Type: 7" Inseam, Size: Large, Color: Light Green
These are nice shorts, free flowing thin but not too thin. Feel nice wearing, easy to move around in them. I like the zipper pockets, things don’t fall out of my pockets now when driving or hiking. These are great wearing while walking, hiking or jogging, really durable. Material is thinner than I’m use to but still nice. These have nice elastic waistband plus a tie, I like this. These are great wearing while playing basketball, has nice are flow and lets skin breath.
