Product Details

The Arco AS12 Zeus Alternator Shield is engineered to protect high-output alternators from damaging voltage spikes and battery disconnect events. This essential protection device prevents costly alternator failures by absorbing voltage transients that occur when batteries are accidentally disconnected while the alternator is charging, or during sudden load changes in marine electrical systems.

Key Features:

  • Protects 12-volt alternators from voltage spikes up to 150+ volts
  • Prevents damage from battery disconnect events during operation
  • Absorbs transient voltage spikes from load dumps
  • Simple inline installation between alternator output and battery
  • Solid-state design with no moving parts for reliable protection
  • Compact, weatherproof construction for marine environments
  • Essential protection for high-output alternators over 100 amps

The Zeus Shield is particularly important in marine applications where battery switches can be accidentally opened under load, or where multiple battery banks and complex charging systems create potential for voltage transients. This device acts as an insurance policy for your expensive high-output alternator, absorbing dangerous voltage spikes before they can damage sensitive internal components.
