Description:
ARCO Zeus AS12 12V Alternator Shield – 18V-60V Voltage Spike & Load Dump Protection
Protect your high-output 12V alternator from damaging voltage spikes and sudden battery disconnect events with the ARCO Zeus AS12 Alternator Shield. Engineered for modern electrical systems, especially lithium battery setups with BMS shutdown risk or accidental switch interruptions, the AS12 instantly clamps excess voltage (18V–60V range) and safely diverts it to ground—preventing costly diode destruction and extending alternator life.
Key Benefits
• Protects against voltage spikes and load dump events
• Ideal for lithium battery systems with BMS shutoff risk
• Extends alternator life by reducing stress on diodes and internal components
• Real-time LED status indicator for instant health monitoring
• Easy installation – mounts directly at alternator terminals in minutes
• Built for high-output alternators and tested to ISO 16750-2 Load Dump Standard
• Up to 75% more survivable in real-world disconnect events vs. leading competitors
• Compact size: 2 × 0.6 × 2 in (50 × 16 × 50 mm)
• IP68 waterproof rated
Perfect for marine, RV, off-grid, and high-amperage 12V charging systems. Works with the ARCO Zeus Bluetooth controller for enhanced voltage sensing on both communicating and non-communicating batteries. Comprehensive protection requires direct voltage sensing.
