Zeus A8000-48V 8kW Vortec Alternator with Isolated Ground & Zeus High-Energy Alternator Regulator

Zeus A8000-48V 8kW Vortec Alternator with Isolated 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 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 are less efficient and limit output at all RPMs. In this scenario, your external smart regulator must drastically reduce the 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 alternator’s lifespan.

Zeus High-Energy Alternator Regulator

ARCO’s Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technician’s configurations. 

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternator’s power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternator’s performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus’ ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

Features:

  • Secure Bluetooth connection
  • Harnesses, Thermistors, and NMEA 2000 kit included
  • Monitors the state of charge
  • Can turn your engine into a dedicated generator with generator mode

Very well-made, nice valet, solid wood with a silicone surface
I really do love this white BROWN wooden valet Tray. It has taken it place right next to my bed on my nightstand. Currently it contains a flashlight, my watch charger, earbuds, remote control, and a walkie-talkie. They all fit perfectly, it really keeps my stand, neat and clean looking. I like these trays because they look so much better than things just laying randomly across your nightstand. It saves things from rolling off to the back of the nightstand against the wall, where I have to flex like an acrobat to reach them. These are perfect for any works surface as well. These would be welcome in the shop. I'm sure they would be great for a teacher, a kitchen a professional at their desk. Just about anywhere you need to put small items and store them temporarily. One of the best things about it is that the bottom or at least the inside surface where you place items is not wooden. It appears to be some type of a silicone so you don't hear that wood sound when you drop things into it. It's soft and things don't roll or slide. It holds them in place exactly where you put them. The bottom came with four felt pads that you can stick on the bottom before you put it on your nightstand or wherever you're putting it. Keeps it from scratching any wooden surfaces. It has a nice rounded edges are very clean dark wood look and a great silicone mat on the inside, this is perfect for your nightstand. I really do enjoy it. Comedy no assembly required. It's well-made and it's a sturdy piece of wood. I highly recommend it.

Holds hubs personal items nicely.
This is a decent sized wooden tray for the price. The manufacturer took care to package this nicely so it was not damaged in transit. All the material used on this tray seem to be pretty decent. The color is very versitile. The wood feels durable and not a soft wood that would easily scratch or dent. The faux leather lining is very nice and makes it quiet when hubs puts his keys down. This tray comes with 4 feet which one must apply by simply peeling the release paper and sticking to the bottom of the tray. This is nice so the tray does not scratch the night stand. Honestly, this tray is very versitile as this can definately be used on an end table in the office or in the bathroom to corral items on the counter top. This is a decent product at a very fair price.
