Product Description

Blue Sea 7601 m‑Series Automatic Charging Relay (M‑ACR)

The Blue Sea Systems 7601 m-Series ACR is a compact, dual-voltage automatic charging relay that intelligently manages the connection of two battery banks. Designed for 12V or 24V systems, it automatically combines batteries during charging and isolates them when not charging or during engine cranking. Ideal for marine, RV, and off-grid power setups, it features Start Isolation (SI) to protect sensitive electronics and a waterproof housing built for demanding environments.

Features

• Automatic Dual-Voltage Sensing: Detects charging on either battery bank and engages/disengages automatically for efficient power management.
• Start Isolation (SI): Prevents sensitive electronics from voltage sags during engine cranking.
• Compact & Waterproof: IP67-rated for immersion protection, ideal for harsh marine or mobile installs.
• Visual Status Indication: Built-in LED shows charging, isolating, undervoltage, and fault modes at a glance.
• Ignition Protected: Meets ISO 8846 and SAE J1171 standards for use in engine compartments and fuel vapor locations.
