Description:
ARCO Zeus AS24 24V Alternator Shield – 30V-90V Voltage Spike & Load Dump Protection
Safeguard your high-output 24V alternator from damaging voltage spikes caused by sudden battery disconnects with the ARCO Zeus AS24 Alternator Shield. Designed for 24-volt systems using lithium batteries (with BMS shutoff risk) or accidental switch interruptions, the AS24 clamps excess voltage in the 30V–90V range and safely diverts it to ground—preventing diode failure and expensive repairs.
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 larger vessels, commercial vehicles, heavy-duty 24V systems, and high-amperage charging applications. Works with the ARCO Zeus Bluetooth controller for enhanced voltage sensing on both communicating and non-communicating batteries. Comprehensive protection requires direct voltage sensing.
