ARCO Marine Zeus 24V 7kW J180 4" Alternator w/Isolated Ground [4503]Zeus 24V 7kW J180 4" Alternator with Isolated Ground The ARCO Zeus 24v 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real world terms, a marine diesel engine at 1,500 RPM with a 2: 1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3. 21: 1 ratio

Zeus 24V 7kW J180 4" Alternator with Isolated Ground

The ARCO Zeus 24v 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!

The ARCO Zeus 24v 7kW alternator turns on for cruising or at mid to higher 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 onthe  alternator lifespan.

A solid and easy to use product.
Worked like a charm. It is extremely durable and easy to use. I bought this item because the one I wanted wasn’t available. I don’t regret getting it.

very nice tool
likes, all aluminum construction, seems very accurate and uses more sturdy 1/4 inch shelf pins instead of the 5mm ones comes with 2 bits which is a huge plus the competition makes you buy the 1/4 drill and only is set up for 5mm to start. this jig will work along side, for now, my other jig dislike is the fact it only has 1/4 pin capability not a deal killer in any way, and it has "pins" to support the jig on the edge again this is both an advantage and disadvantage as you can change the depth of where the pins are located BUT if you are making something smaller the jig may not calibrate consistently. on another positive you can replace the bits easily and commonly as they are not proprietary and simply standard 1/4 inch bits this will be a fine addition to my other goingmake tools and future ones

Sturdy and well made
I have yet to use this jig, but on initial inspection it is well made and no doubt will withstand a lot of use. The machining of the threads was rough on the one I received, but after screwing in the guides a couple times the operation became smoother. Probably lack of cleanup after anodizing left in the threads. Other than that it looks like it will be useful and longer lasting than many of the plastic jigs out there.

Easy to use
I built a bookshelf for my grandson and wanted adjustable shelves. This jig did the trick. Very easy to use, and a lot of adjustability. I have other tools by goingmake and they all are well made and affordable.

Works very well and holds up over time!
This works really well for drilling out shelf pins! The drill bit that comes with it is a good quality bit, and the holes in the metal block are very strong, The drill bit doesn't even come close to cutting into them. I have drilled about 1000 holes with it so far, and it still works as good as it did when it was brand new! I would definitely recommend this over the plastic ones. It's very easy to use, as well.
