Zeus A8000-48V 8kW J180 4" Alternator with Isolated Ground & Zeus High-Energy Alternator Regulator

Zeus A8000-48V 8kW J180 4" 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
  • Pre-set battery libraries
  • Data logging and sharing
  • CAN bus and NMEA 2000-integrated networks

A thoroughly-researched, thoughtful, and nuanced work about the 1692 Salem withcraft panic.
Format: Paperback
This graphic novel recounts the 1692 Salem (Massachusetts) witchcraft panic that engulfed Salem, Salem Village (now Danvers), and adjacent communities. About two dozen men and women were convicted and hanged, one was pressed to death (tortured) to try to force him to acknowledge the Court’s authority. That man was Giles Corey, aged 80. The book focuses on him, but it covers others among the accused and executed as well as on the judges, politicians, and other involved. (No so much on the accusers and their motives.). The narrative plays out chronologically with interstitial vignettes in which 19th Century literary figures Nathaniel Hawthorne and Henry Wadsworth Longfellow wander around Salem during the 1800s discussing the trials and their legacy. (Hawthorne lived in Salem for a time and was a descendant or the Court of Oyer and Terminer Judge Hathorne.). The work concludes with a chapter, More Wonders of the Invisible World, that follows how Salem developed economically up to the present day in which witchcraft-related Halloween tourism turns Salem town into arguably the least attractive “tourist attraction” on Cape Ann. (Do not skip this chapter, it is engrossing.) An extensive series of endnotes provide scholarly references and background information. The artwork veers back and forth between caricatures (the 17th century events) and realism (19th century and onwards). In both cases the line art is exquisite. The text includes quotes from transcripts of the trials and other contemporary documents as well as fictional dialog. Wickey worked on this book for more than a decade, and it shows in his thorough scholarship. This is, in all seriousness, Pulitzer/Eisner-level work. Wickey was born in Beverly and resides on Cape Ann. Most of us born and raised on the “North Shore” learn about the Salem witchcraft panic in high school -often as a cautionary tale about politics, spectral evidence, and what we would today call “lawfare.” I thought I knew a fair amount about the 1692 panic, but I learned something new with nearly every other page. I was especially glad to see Wickey cover now-debunked ergot-poisoning theory and that he dismissed the vile slander that some among the convicted and executed were actually witches. There’s nothing really “missing” from the book, though one wishes one could learn more about the fates of the accusers other than Ann Putnam. That their motives appear to have been “sport” is bone-chilling fully three centuries later. Read her "apology" years later and try not to think, "psychopath." At 500 plus pages, it's too long to read at one setting, but it is a pleasure to read at shorter intervals.

Masterpiece
Format: Kindle
It has been said that any work of literature should be gauged upon how much the work makes the reader think. Ben Wickey has certainly achieved this - in spades - as one of the “civilised” world’s most frightening episodes is revisited with respect and thoughtfulness on the human condition.

The Tale of Salem
Format: Paperback
If you’re not familiar with the history of Salem and its witch trials, this graphic novel is a solid entry point. The author, while not a historian, clearly put in the work—spending time in Salem, connecting with residents, and striving to honor both the historical record and the modern-day sentiments of those who live with that legacy. His goal was to get the facts right while also capturing how the people of Salem view their own history, and I think he succeeded in that respect. The artwork fits the subject matter well. We often imagine people of that time as living hard, joyless lives, and the art conveys that sense of austerity. The mix of black-and-white and color panels is sometimes striking—there are moments where the color really enhances the impact of a scene—but other times I wasn’t sure what it added. Still, the black-and-white aesthetic ties neatly into the grim tone of the era. That said, the book is quite long, and if you’re already well-versed in the Salem Witch Trials, you may not learn much new in terms of facts. But if you enjoy studying the trials or want to explore the story through a different medium, this graphic novel is definitely worth picking up. For me, it landed at a 3.5 stars, which I’ll round up to 4 (since I usually do that when posting on review sites).

Salem's a Lot
Format: Paperback
Great comic that deserves to be at the top end of best of 2025 lists. Intensively researched with multiple art approaches to the varied settings. It also made me want to take a trip to Salem in the off-season. A virtuosic undertaking!
