Protect your alternator from the risks of modern energy systems.
With the rise of lithium batteries and high output alternators On-board systems are becoming increasingly powerful, but also more susceptible to voltage spikes. A sudden interruption, for example by a BMS intervening or a battery switch being turned off, can cause a so-called load dump. In such a situation, the voltage can rise rapidly and cause serious damage to the alternator and other on-board electronics in a fraction of a second.
The ARCO Zeus Alternator Shield is developed to solve precisely this problem. The system continuously monitors the voltage and intervenes immediately as soon as a surge occurs. Excess energy is safely discharged to earth, protecting the vulnerable components of your dynamo. This not only prevents costly damage but also ensures that your charging system continues to function reliably, precisely at the moments when you need to be able to depend on it.
The Shield is particularly interesting when combined with lithium battery banks and high-output alternators, such as those from ARCO or Electromaax. In these types of installations, the currents are higher and the risks are greater, making an extra layer of protection far from a luxury. At the same time, installation is simple: the unit connects directly to the alternator and operates fully automatically, without any need to adjust settings.
What you get is peace of mind. No more worries about unexpected voltage spikes or damaged diodes, but a stable and protected system that is ready for intensive use, both on the water and in off-grid applications.
High standards
As you would expect from ARCO, the Alternator Shield is built for tough conditions and tested to high standards. It is therefore a logical addition to any modern onboard power installation. Available for 12, 24 and 48V systems.
