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 allows 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

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.

Choose your shape
Size: Medium, Color: Duo Pack
I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this

My dog likes it!
Size: Medium, Color: Antler, Size: Medium, Color: Antler
My aggressive chewer loves it! I have a 20 pound rat terrier ....small was recommended, but we went with a medium. He went to work on it right away. He is not picky about chew bones but it makes me feel better that it is a natural material. The chewed photo is about 30 mins after giving it to him.
