AS12 - Arco Marine ARCO Zeus Alternator Shield - 12V

Zeus Alternator Shield - 12V

Protect Your Alternator from Voltage Spikes & Disconnect Events

The ARCO Zeus Alternator Shield is engineered to protect high-output alternators from damaging voltage spikes caused by sudden battery disconnect events. These events, commonly triggered by lithium battery BMS shutdowns or accidental switch interruptions, can instantly destroy alternator diodes. 

The Shield clamps excess voltage and safely diverts it to ground, helping extend alternator life and prevent costly failures.

Key Benefits:

• Protects Against Voltage Spikes - Prevents damage caused by battery disconnects and load dump events
• Designed for Modern Electrical Systems - Ideal for lithium battery systems with BMS shutoff risk
• Extends Alternator Life - Reduces stress on diodes and internal components
• Real-Time Status Indication - LED indicator provides instant health status
• Easy Installation - Installs directly at alternator terminals in minutes
• Built for High Output Systems - Engineered to perform with today’s high-amperage alternators

ARCO Advantage:

• Tested to ISO 16750-2 Load Dump Standard
• Up to 75% more survivable disconnect events vs. the leading competitor
• Designed to handle real-world high-output charging conditions
• Integrated into the ARCO Zeus ecosystem

The ARCO Zeus Alternator Shield (part number AS12) is a protective accessory designed for 12V alternators. This component is suitable for IT hardware resellers and businesses that manage or maintain marine equipment with ARCO Marine parts. Its primary function is to offer a layer of defense for the alternator, which can be critical in environments where the generator system is exposed to potential damage or wear. By shielding the alternator, it helps mitigate risks that could lead to system downtime or the need for premature component replacement. This product is intended for buyers who require specific ARCO Marine generator parts and accessories to maintain operational continuity and protect existing 12V alternator installations.
