Blue Sea Systems ML-ACR 12V Automatic Charging Relay | 500A Smart Battery IsolatorEffortlessly manage dual battery banks with the Blue Sea Systems ML-ACR Automatic Charging Relay. This 12V, 500A heavy-duty isolator intelligently combines batteries for charging and isolates them during discharge, preventing dead start batteries. Featuring low power consumption via magnetic latching technology and essential manual override for emergency starts or service. Built tough for marine and RV use, it´s IP66 waterproof and ignition-protected, ensuring reliability and peace of mind in demanding environments.Ultimate Power Management for Marine and Vehicle ApplicationsTake command of your vessel or vehicle´s electrical system with the unparalleled intelligence and reliability of the Blue Sea Systems ML-ACR. Designed for boaters, RV owners, and commercial vehicle operators who demand the best, this automatic charging relay eliminates the complex guesswork of managing multiple battery banks. Its primary function is to preserve your engine start battery, ensuring you always have the power to get going. When your alternator or battery charger is active, the ML-ACR automatically senses the charging voltage and combines the start and house battery banks, allowing both to be charged simultaneously from a single source. Once you shut down the engine and the charging stops, it automatically isolates the batteries. This critical function allows you to use your house battery for lights, stereos, and other accessories without any risk of draining the battery needed to start your engine.The heart of this unit´s efficiency is its advanced magnetic latching technology. Unlike traditional relays that require constant power to remain closed, the ML-ACR draws a significant current only for a moment when switching states (open or closed) and then uses magnets to hold its position, consuming virtually zero power. This ultra-low power consumption is vital for conserving precious battery capacity, especially during extended periods away from shore power or on the hook. Built for the harshest conditions, this robust unit is engineered to provide years of flawless service, giving you the confidence to venture further and stay out longer.Main Features* Automatic Dual Battery Management: Intelligently combines and isolates 12V battery banks based on charging status.* 500 Ampere Continuous Rating: Engineered to handle high-output alternators and large battery bank loads without failure.* Magnetic Latching (ML) Technology: Consumes power only when switching, resulting in near-zero current draw and maximizing battery life.* Manual Control Override: A robust manual knob allows for locking the relay open or closed for maintenance or emergency situations, such as combining batteries for an emergency engine start.* Start Isolation (SI): Protects sensitive electronics from voltage sags and spikes during engine cranking.* Engine Isolation (EI): Allows for manual isolation of battery banks even while the engine is running.* Remote Control and LED Output: Features a connection for an optional remote-mounted switch and an output to power a remote LED, indicating the relay´s status on your dashboard.* IP66 Waterproof Rating: Sealed case design protects against powerful water jets, ensuring reliability in wet bilge and engine room environments.* Ignition Protection: Certified as safe for installation in gasoline engine compartments.Product Attributes* Category: Electronics* Subcategory: Electrical Connections* Type: IsolatorsTechnical Specifications* Nominal Voltage: 12V DC* Amperage Rating (Continuous): 500A* Amperage Rating (Intermittent, 5 min): 700A* Cranking Rating (30 sec): 1.450A* Switching Technology: Magnetic Latching Relay* Control Current Draw (Open or Closed): 0mA (zero)* Ingress Protection: IP66 Waterproof* Safety Standards: Meets ISO 8846 and SAE J1171 for ignition protection* Terminal Stud Size: 3/8-16 (M10) Tin-Plated Copper* Live Current Switching: 300A 12V DC - 10.000 Cycles. tradeinn Waveinn
