Product Description Blue Sea Systems 7610 SI‑Series Automatic Charging Relay – 120A ACR The Blue Sea Systems 7610 SI‑Series Automatic Charging Relay (ACR) is a high‑capacity battery combiner designed for 12 V and 24 V systems with alternators up to 120 A. It automatically connects battery banks during charging and isolates them during discharge or engine crank to protect sensitive electronics. Features Automatic Battery Combining: Smart, dual‑sensing relay combines batteries when one bank is charging and isolates them when charging stops or engine cranks. Start‑Isolation Protection: Prevents voltage sags or spikes to house loads during engine start-up. High Amp Capacity: Rated 120 A continuous, 210 A intermittent (5 min), suitable for high-output alternators. Marine‑Grade Build: 12/24 V auto-ranging; hermetically sealed, ignition-protected enclosure; IP67 waterproof rating. LED Remote Indicator: Offers optional remote LED output to display ACR state (combine, isolate, cranking, undervoltage). Waterproof and Durable: Protected against temporary submersion; clip-on insulating cover; tin-plated copper studs. Specifications Nominal Voltage: 12/24 V DC (auto-ranging) Continuous Rating: 120 A; Intermittent: 210 A (5 minutes) Operating Current: Combined 175 mA / Open 15 mA Studs: 3/8‑16 (M10), 7/8″ length, suitable for up to 1/0 AWG cable Dimensions & Weight: Approx. 0.57 kg (1.25 lb) Applications Marine or RV dual battery systems with high-output alternators Off-grid electrical systems, solar panels, emergency generators Protecting sensitive electronics during engine crank via start-isolation Any dual-battery configuration needing robust automatic combiner control The Blue Sea 7610 SI‑ACR delivers intelligent battery management with rugged, marine-grade protection—ideal for serious boaters, RVers, and off‑grid enthusiasts seeking reliable, automated charging performance.
