The ARCO Marine Zeus 48V Alternator Shield is designed to protect high-output alternators from voltage spikes and damaging disconnect events. When lithium battery BMS shutdowns or accidental switch interruptions occur, the shield clamps excess voltage and diverts it to ground to prevent diode failure and extend the life of your alternator.

• Protects against voltage spikes and load dump events
• Ideal for modern systems using lithium batteries with BMS
• Features real-time LED status indication
• Engineered for high-amperage, high-output systems
• Tested to ISO 16750-2 Load Dump Standard
• Easy installation at alternator terminals

This unit is designed to provide improved survivability during disconnect events and integrates into the ARCO Zeus electrical ecosystem. Model number: AS48.
