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 competitors 48V alternators, having a direct impact on the alternators lifespan.

Very convenient
Size: 2.1 Fl Oz (Pack of 1)
A great size to carry in your purse or car. My only complaint is it doesn’t make a nice mist so I have to rub it in, or spray it on my hands and pat it on. Smells good and works great.

My favorite facial sunscreen
Size: 2.1 Fl Oz (Pack of 1)
I love this sunscreen mist for the face. I have tried many facial sunscreens to protect against the Arizona sun and this is by far the best. So many sunscreens have a heavy feel, make my face sweat more, and end up clogging my pores. This sunscreen has a light, pleasant smell and is a lightweight spray. You spray it into your hand and smooth it on your face and neck. It feels hydrating without any heavy or greasy feel, and you can use foundation over it if you wish. It has done a great job protecting my skin, and just as important for me, it does not clog my pores and cause complexion issues. I have pretty sensitive facial skin and this has not caused any irritation at all. It is definitely worth trying and then buying again when you love it.

Not great
Size: 2.1 Fl Oz (Pack of 1)
I wish I could give 3 1/2 starts but I have to give it 3 stars for two reasons. 1 is it is not a fine mist, it will leave your face looking crazy after you spray it. You end up having to pay it into your skin because there’s white splotches all over your face. So if you were to apply this with no mirror it would be a problem. Also I feel like it semi defeats the point of using a face spray if you have to use your hands to finish applying it. 2 is that for me it makes my skin feel hot and kinda burn around my mouth area. I think there might be too much fragrance or something. It does go away after awhile but it is not pleasant and I can’t imagine it is good for me.

Great for summer pool time
Size: 2.1 Fl Oz (Pack of 1)
Gave it 5 stars because it really does its job. I used this sunscreen on my face during the summer when I was going to the pool a lot. It goes on white at first, but once you rub it in well the white cast pretty much disappears. Doesn’t make my face super greasy and protected my skin really well, no burns, no weird tan lines, nothing, as long as I reapplied it like the instructions say. The smell is light and not annoying. The bottle is small and easy to keep in a bag. Overall, a good product that actually works.
