Zeus 24V 4kW Low Turn On (LTO) N62 Alternator with Clutch Pulley & Zeus High-Energy Alternator Regulator

Zeus 24V 4kW Low Turn On (LTO) N62 Alternator with Clutch Pulley

The ARCO Zeus 24V 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24V 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor 24V alternators utilize a 12V rotor and field current, which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor 24V alternators, which directly impacts 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

This Pillow Is A Must Buy!! What Are You Waiting For?
Size: Queen (Pack of 1)
This is, without a doubt, the best pillow I have ever owned. One of my favorite features is the adjustable shredded memory foam fill, which allows you to customize the loft and firmness by adding or removing foam to suit your sleeping preferences. As both a side and back sleeper, I found it incredibly comfortable and supportive. The overall quality is excellent, from the materials used in the pillow itself to the thoughtful packaging. The removable cover is washable, although I personally use a pillowcase to keep it protected. I also appreciated that extra foam is included, making it easy to fine-tune the pillow over time. The difference in my sleep quality was noticeable from the very first night. I’ve been sleeping more comfortably and waking up feeling more rested ever since I started using it. Considering the quality, comfort, and customization options, I believe the $75 price point is well worth it. I am so impressed with this pillow that I plan to purchase another one in the future.

This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability
Size: Queen (Pack of 1), Size: Queen (Pack of 1)
I purchased the DreamyBlue Signature Adjustable Pillow for my husband because he often experiences back discomfort, and many of the pillows we had previously would become flat and lose their support over time. This pillow has exceeded our expectations. It is incredibly soft, comfortable, and comes with extra filling, which allows you to adjust the firmness to your personal preference. We really appreciated having that option. Even after extended use, the pillow has maintained its shape much better than other pillows we've owned. It provides a plush, cozy feel while still offering good support. My husband finds it very comfortable, and it has quickly become his favorite pillow. This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability. I would definitely recommend it.

Finally Found a Pillow Worth Keeping
Size: Queen (Pack of 1)
I genuinely feel like I’ve tried every pillow on the market. At one point, I thought Amazon was going to flag my account because I bought and returned so many pillows trying to find the right one. This is the only pillow that made the cut. The shredded memory foam filling makes a huge difference because the pillow is both soft and supportive, while still being adjustable to fit the way you sleep. It arrives extremely full and plush, and it even comes with an extra bag of fill, which honestly surprised me. I ended up removing about half of the filling to get it exactly how I wanted it. I’m a side/stomach sleeper, which can make finding a good pillow difficult since most are either too thick or too flat. This one was perfect because I could shape it exactly how I sleep. It stays cool throughout the night, has a slightly heavier premium feel, and feels much higher quality than most pillows I’ve tried. Super comfortable, supportive, and customizable. I would absolutely recommend it and would definitely buy it again

A bit expensive
Size: Queen (Pack of 1)
Waited to give a review on this one because I needed several nights before I had any idea if it was as good as everyone says. I've had a real problem finding pillows lately. Either they're too soft to provide support and I wake up with a stiff neck or they're too sturdy and I wake up with a stiff neck. Contour pillows have worked best for me, but they fall under the category of too sturdy. I also toss and turn too much at night, which means I always end up in an awkward position with contour pillows. So I took a chance on an obscenely expensive pillow, and yes, that is the reason for one less star. I'd happily pay $70 for a pillow I thought was amazing and comfortable and perfect, but this one wasn't quite it. It IS comfortable. I have slept on it for a month now without it making my neck stiff, so it does actually provide a good balance between soft and sturdy. They make it easy to stuff the pillow to your preferred fluffiness and even provide extra stuffing if you need it, which adds to the degree of comfort. While the pillow does provide good neck support, I toss and turn a bit trying to find a comfortable position when I first try to sleep. The stuffing within the pillow moves around at night, most notably shifting to the side and the pillow is notably flatter now than when I first purchased it. You can fluff it out, similarly to a down pillow, but it doesn't seem to retain its shape on its own. In some ways, that's good because what it does instead is try to retain a shape that fits you. So yes, this is a really good pillow. One of the better ones you can buy. But it's really expensive for a pillow.

Best pillow I've ever had
Size: Queen (Pack of 1)
I don't really write reviews but holy buckets, Batman. This pillow is legit. Back, neck, and shoulder pain is nothing new for me; I've had scoliosis since I was a kid and hyperflexibility in my neck since birth leading to frequent muscle spasms that have caused me to miss work. Guys. This pillow. It is the most comfortable pillow I've ever had. Like, my neck doesn't hurt and I genuinely didn't remember what that felt like. It's simultaneously supportive and soft and it doesn't sink in. The instructions are super clear to understand and the pillow fluffs up no problem if it gets a little flat. This is a game changer for me and I so hope anyone who buys this has the same experience.
