ARCO Marine Zeus A8000-48V 8kW Vortec Alternator w/Case Ground [4606]Zeus A8000 48V 8kW Vortec Alternator with Case Ground The ARCO Zeus A8000 48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps)at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real world terms, a marine diesel engine charging at 1,200 RPM with a 3. 13: 1 pulley ratio is generating just over 5kW

Zeus A8000-48V 8kW Vortec Alternator with Case Ground

The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps)at  2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!

Instead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitor’s 48V alternators, having a direct impact on the alternator’s lifespan.

8oz Size Perfect for Small Amounts of Milk
Size: 6.8oz/200ml Silver
This is a quality pitcher with a nice weight to it. I only use 80ml of milk in my cappuccinos and had trouble getting a good microfoam when using a larger pitcher. This little 8oz pitcher is the perfect size and makes it easier to achieve microfoam. The only potential issue I see is the pitcher may overflow if using more than 80ml although this may be due to my technique.

Pretty and functional
Size: 6.8oz/200ml Matte Black
I really liked the size and functionality of this milk pitcher, it’s really elegant looking as well. I use it for when I want to make an iced coffee that I need to mix stuff with and it holds a good amount of coffee. Easy to clean and pour as well, for what I paid I think it’s worth it.

Small, works with (some) induction units, just what I needed.
Size: 6.8oz/200ml Silver
It's small and the good thing about it is that it works with my induction (Nuwave Flex Precision, 1,300W.) Not perfectly, but will work. It doesn't work with my larger Duxtop (9600LS/BT-200DZ, 1,800W) because it is looking for more metal to sense before it can trigger the induction function. So, if you have a smaller induction unit it might work. If not, get a CozyKit 5.5" induction diffuser (on Amazon) and heat it up on that via induction. That diffuser should work on any induction unit. I guess we can't do links anymore even if on Amazon?? from attempting to post other reviews, so this is the text discr for the diffuser on Amazon, it's hard to find the smaller one otherwise: (Heat Diffuser Stainless Steel Induction Adapter Plate Removable Handle Coffee Milk Cookware Induction Hob Heat Cooking Diffuser for Electric Stove 5.5inch)
