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

I like the wood and metal look. The pencil cup was easy to put together and it is sturdy. It is great to have some organization on your desk.

The Best Cable Management Solution for IT Work — Reusable, Reliable, and Professional
Size: 150Pk - 8" x 1/2", Style: Cord Wrap Cable Ties, Color: Black and Gray
TL;DR: I’ve been using these VELCRO Brand cable ties for years as an IT field tech. They hold tight, are endlessly reusable, and keep cables tidy. Great for both home and professional setups. Full Review: As an IT field technician, I’ve tried countless ways to keep cables organized, and these VELCRO Brand cable ties are simply the best. They’re reusable, strong, and easy to reposition — ideal for network racks, AV installs, or just cleaning up cords around the house. Functionality: Top-notch. The hook-and-loop material is aggressive enough to hold firmly, but not so sticky that it clings to everything else in your tool bag. They wrap cleanly, stay put, and release easily when you need to re-route cables. They’re reliable enough for professional jobs and flexible enough for home use. Storage Capacity: Each strap holds more than you’d expect — I rarely need to link two together. They handle thick cable bundles or power cords just fine on their own. And when I do need more length, it’s easy to join a second strap for a larger wrap. The two-color mix (black and gray) is great for keeping different cable types separated — for instance, network vs. power. The thin profile also helps keep bundles neat and professional-looking. These have earned me plenty of compliments from higher-ups for clean cable runs and well-organized setups. Once you switch to these, you’ll never want to deal with cutting zip ties again.

VELCRO Ties Are the Standard to Rely On
Size: 150Pk - 8" x 1/2", Style: Cord Wrap Cable Ties, Color: Black and Gray
I am a big fan of VELCRO brand products because of their quality and utility. I have used their rolls of Velcro hook and loop tape as well as their little patches, and I became a brand loyalist. Yes, there are many other manufacturers, but these are certainly as good as it gets. This product is your very basic, very thin, and very copious supply (for my neighbors in Rio Linda - that means plenty of them). You get two big spools of these little eight (8) inch ties that are adhesive throughout their length - that means you can tie the smallest cables to anything almost up to their full length. If you need a longer wrap - use more than one and just extend the length by piggy backing them. The real advantage of this bulk package is that you are not tempted to save some for later - you have enough to use as many as you like and can happily go tie crazy on all your cords! It's VELCRO party time. We live in an electronic age, and I have a lot of more pricey hook-and-loop specialty ties, and I try to keep a few back as spares. Forget that - with these little ties, I can actually use them and do what I need to get those tangled cords in shape. O.K. maybe I am a geek, but I cook my chicken - dead already, and I believe in independent segregated wiring and not tripping over things or spending time untangling messes when I need to move gear. These big rolls will make your life easier - I use them to attach notes to little jars or vials - to tie two gloves together when I am not wearing them - and other uses even cutting them into smaller pieces. That's one of the advantages of these bulk spools - lots of supply. Yes, the individual ties are dinky thin little things, but they hold very well (why you buy genuine VELCRO) and you don't feel stupid using them up on anything you feel like. They are expendable, and that adds to their ultimate utility. Darned useful product. Buy it - use it; enjoy.

Computers, electronics cabling? You NEED these!
Size: 100Pk - 6” x ½”, Style: Cord Wrap Cable Ties, Color: Black
If you do any cabling, be it TV or computer or anything else, these ARE worth there weight in gold. Seriously! They'll keep your cable runs, extension cords, etc in a nice neat easy to work with bundle that you can have out of the way. Adhesion is very good also which is also important. Just the right size for most applications and if you need something large they make them to fit your needs. Cable management has always been a pet peeve of mine and makes a difference that not only shows but makes future work and maintenance much easier. Whenever I see a rat's nest cluster of wires I always know it means shoddy workmanship!

Very Effective, but Not the Instructions
Size: 150Pk - 8" x 1/2", Style: Cord Wrap Cable Ties, Color: Black and Gray
These work very well, but when you remove them from the box, you see two donuts, one grey, one black, of 75 tightly wrapped cable ties each. So far, so good. First deficiency: The "how to use" pictures---three of them---are tiny light line drawings in 7/16" x 7/16" boxes. If you don't have a 400-power microscope, maybe a magnifying glass will do. Maybe Velcro---a "name" brand that should know better---thinks that the use of these devices is obvious. Well, "obvious" is obvious only when it's obvious, and that can vary from person to person. They should assume nothing. Second deficiency: Before trying (and, one hopes, succeeding) at using these ties, one must determine exactly now to remove the first tie from the outside of either donut. Obvious? No, not really, because, as it turned out, it requires some effort to remove the first one---the placement and circumstances of which do not at all (not on my set of these, anyway) suggest in any concrete way which one should be taken first. No one wants to tear up a couple of ties just to figure out how not to tear up ties by removing them incorrectly or out of order. The punishment here is four stars that could have been five.
