Key Features & Benefits:

• Automatic Battery Management: Combines batteries for efficient charging and isolates them during discharge or engine start to protect sensitive electronics.
• Ultra-Low Power Consumption: Magnetic Latch (ML) technology draws less than 40mA in ON or OFF states, conserving precious battery power.
• Manual Control with Lock-Off: Provides an essential safety feature, allowing control independently of power and offering a LOCK OFF for secure servicing.
• High Continuous Rating: Boasts a 500A continuous current rating, capable of supporting high-output alternators and demanding marine applications.
• Dual Sensing Capability: Intelligently senses charge on both battery banks, optimizing charging efficiency and battery health.
• Start and Engine Isolation: Configurable Start Isolation (SI) protects house loads during engine cranking, while Engine Isolation (EI) safeguards engine electronics when running two engines.
• Robust Deutsch DTM Connector: Ensures a secure and reliable connection for the control circuit, built to withstand harsh marine environments.
• Durable Terminal Construction: Features 3/8"-16 tin-plated copper studs for maximum conductivity and superior corrosion resistance, accommodating multiple cable terminals.
• Live Load Switching: Silver alloy contacts provide high reliability for safely switching live loads, ensuring longevity and performance.
• Remote Status Indication: LED output allows for remote monitoring of battery status, indicating when batteries are combined, isolated, or in lockout.
• Includes Remote Control: Comes with an ML-Series Remote Control Contura Switch (PN 2146) for convenient operation.

Recommended Applications: Ideal for multi-battery bank systems in marine vessels, RVs, and other demanding 12V DC applications requiring intelligent power management.
