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
  • Pre-set battery libraries
  • Data logging and sharing
  • CAN bus and NMEA 2000-integrated networks
  • Compatible with all voltage systems (12- 48V)
  • IP66 & IP67 rated

Perfect for a midi keyboard music setup
Style: 8-in-1
I bought this to setup a midi keyboard for the worship team. I connect a couple ipads and the keyboard and it works great. It powers all the devices, has good length for the power cord and just works as intended. What else is there to say. It's a good product.

Lots of ports, and lots of power!
Style: 8-in-1
I was in search of a hub that not only had a large number of USB A and USB C ports but also was externally powered, so that it can give some power to all the things plugged into and take a little load off of the laptop. It is working great and I would recommend.

Anker 8 in 1 USB Hub excellent choice!
Style: 8-in-1
I’m always expecting more for my laptop power supply than it can do. I bought this hub because I needed powered connections not only to reduce the strain on my power supply but also help them operate more effectively. The Anker USB hub 8 in 1 solved the dilemma, highly recommend.

It does exactly what's advertised, which is perform poorly
Style: 8-in-1
1 star because it does exactly what's advertised if you scrutinize the listing, but what it does is so mind numbingly stupid nobody would assume it's this poor of a product. It comes with a stand alone power input, but to use it properly you need an additional USBC power supply to feed into it, and oh yeah also most of the USBC ports deliver low power, and the USBA ports deliver no power. This is like a weird peripheral stuck in a time warp torn between 1998 and the modern day. Nobody is asking for this and the subtlety of how dumb this design is is reflected by the "Frequently returned item" disclaimer. Whoever product managed this needs to rethink their career

Worked fine.
Style: 8-in-1
When I tried to plug in our new backup hard drive, I got a message saying something like "USB power exceeded." Bought this, plugged it in, attached the hard drive, no problems since.
