Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground & Zeus High-Energy Alternator Regulator

Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground

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
  • Pre-set battery libraries
  • Data logging and sharing

Love it! Can’t wait to buy a second one!
Size: Left Facing, Size: Left Facing
Worth every penny!! This rack is pricy, but it’s awesome. Definitely wish the price was a little better, but I still plan on buying a second one to fit more of my spices. Super easy to install and the glide feature is really smooth. Bottles and lids are quality material and overall really pretty design. Love that it comes with TONS of spice label options for every spice you could imagine! Fit in my standard depth cabinet that is 12” deep (and I have inset cabinet doors and there was still plenty of room for it). You can easily pull it out and read the labels.

Aesthetic & Functional
Size: Left Facing
Good use of vertical space. It feels very secure and sturdy once mounted. It comes with everything you need, there’s a label for every spice and variation of that spice you can think of (different labels for the same spice but whole vs ground) and plenty of jars, with a few extra. Very well thought out. The tops were also standard enough to fit some of my existing spice jars so I didn’t even need to transfer those ones I just swapped lids and/or added a label. I previously had a different pull out spice rack with two flat shelves but it was a pain to find a specific spice without moving some out of the way, and it held maybe half as many jars as this one. This is an easy organization project that will free up a ton of horizontal cabinet space and makes finding spices while cooking significantly easier. If you do want to use your existing jars, make sure they have a flat side, as cylinder shaped jars roll around a bit when you slide it out. I just transferred my spices with round jars into the provided jars so wasn’t an issue for me! Really great value, especially considering how much the kit comes with!

Organization Heaven
Style: Three 2"W Drawers, 2-Tier
These spice racks have revolutionized my cabinet. I have very shallow slim cabinets and these racks have helped to organize and contain all my cooking spices/oils in one cabinet. The cabinet is now visually appealing and organized. The labels for the side facing you are a big plus as you can tell which spices are on each shelf without pulling the shelf all the way out.

Quality made and work perfectly!
Style: Three 2"W Drawers, 2-Tier
These maximize your space! I have very few upper kitchen cabinets so I really have to be organize and use things to help with space. These work great! My husband installed 3 of them in a small cabinet just to the left of my cook top. My spices are right where I need them! These are sturdy and work well, slide very easily. Spices fit nicely. They seemed a little pricey, but after they were installed, I feel they are well worth it.

Easy to install, but rub against each other when pulled out
Style: Three 2"W Drawers, 2-Tier, Style: Three 2"W Drawers, 2-Tier
These look nice, they are easy to install, and are functional. Only reason for not giving a 5 star is due to what appears to be a somewhat bent rail. When pulled out (extended) the top of the second row rub against each other causing the motion to not be smooth.
