Blue Sea Systems m-Series ACR, 12/24V DC 65 Amp, Ignition Protected

Optimize your dual-battery system's performance and longevity with the Blue Sea Systems m-Series Automatic Charging Relay (ACR). This intelligent charging relay seamlessly manages the connection and isolation of two battery banks, ensuring that your primary and auxiliary batteries are efficiently charged while protecting sensitive electronics. Ideal for marine, RV, and off-grid power setups, it's an essential upgrade for reliable power management. Invest in intelligent battery charging today for unparalleled peace of mind.

• Automatic Dual-Voltage Sensing: Intelligently detects charging on either battery bank and automatically combines them for efficient power distribution, then isolates them during discharge or engine cranking.
• 65 Amp Continuous Rating: Expertly manages charging currents from alternators up to 65 Amps, commonly found in outboards and many inboard engines.
• Start Isolation (SI): Safeguards sensitive onboard electronics by temporarily isolating house loads from the engine circuit during cranking, preventing voltage sags and spikes.
• Compact & Versatile Mounting: Its small footprint allows for flexible surface, rear, or panel installation to suit your specific application.
• IP67 Waterproof Rating: Ensures robust protection against temporary immersion, making it ideal for demanding marine and outdoor environments.
• Ignition Protected: Meets ISO 8846 and SAE J1171 standards, ensuring safe installation within gasoline-powered engine compartments.
• Visual Status Indication: A built-in LED provides clear, at-a-glance status of the ACR's operation, including charging, isolating, undervoltage, and fault modes.
• Snap-On Terminal Cover: Insulates terminal connections to prevent accidental shorts and enhance safety.
• Wide Voltage Compatibility: Operates effectively in both 12V DC and 24V DC systems.
• Robust Cable Support: Accommodates maximum cable sizes up to 1/0 AWG for secure and high-current connections.
• High Intermittent Rating: Handles 115A for 5 minutes to manage temporary higher electrical demands.

Designed for any dual battery setup in marine vessels, RVs, and off-grid power systems. For emergency starting, consider pairing with a battery switching system that includes a combine batteries/parallel function.
