Zeus 24V 4kW Low Turn On (LTO) J180 4 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.

like that
Size: 48in, Color: 3tier, Size: 48in, Color: 3tier
I like to have a three-dimensional wall shelf at home. I can display plants, photos and other items well. It is great. I haven't taken care of it yet. I need to put more beautiful items. Oh, by the way, it is of good quality. It is a little heavy. The merchant provides expansion screws for hanging it on the wall. It is also very simple to assemble... I am very satisfied with the effect and I like it very much.

Great Accent Piece
Size: 48in, Color: 3tier
Industrial looking with wide shelf space. We were looking for a functional accent piece that we can also put things on. This new addition has been more than perfect. It provides a rustic feel and it has the industrial bars that holds the shelves which is the best. Very sturdy, please make sure to assemble on studs this piece is heavy. It looks really good in our living area.

It takes skill to mount and not have the leaning tower of Pisa
Size: 36in, Color: 4-layer
First, the product is beautiful! I purchased this one for a smaller wall location but realized it was more massive and commanding within a room - That ended up being a good thing as I decided to put it in my office where my L shaped desk, (a Vernal executive desk), being quite massive, was successfully offset by drawing the eye up to the wall behind the desk where I had this mounted - In essence, the room was now properly balanced with the large desk - One should also know it takes some skill to mount to the wall - It should be in studs - You have to use a balance or bubble level to first get the vertical pipes parallel to each other - Also, make sure both vertical pipe supports are symmetrically matching each other from one side to the other - If you mount one upside down the wood shelves won’t lay level - We also turned the pipe supports so that the shelves would be equal distant - If I recall, if they are turned the other direction , you end up with shelves that are not equal distant with 2 shelves ending up closer to each other than the remaining shelves. The shelving is very high quality and I was very, very pleased with the end result and how the whole room was balanced with the large desk in a smaller office space.

Solid shelves that look good!
Size: 36in, Color: 3-layer, Size: 36in, Color: 3-layer
Got these as a focal piece to my basement bar (added some cheap stick on LED strip lights behind it). I’m glad I ordered these! They are sturdy, shelves are solid wood, and the overall quality of the shelves is great. They were easy to install with provided hardware (although there isn’t much instruction in terms of mounting them, just putting them together), but it was simple enough to figure out with two people and a level (one holding, one making marks). Each pipe end has 4 screw holes, so expect to put 16 holes in your wall, but as shown in the photos the shelves can hold a good amount of weight. I recommend these for anyone looking to add the industrial look to your wall with a quality built shelf.
