Maretron MPower CLMD12 12-Channel DC Load Controller Module with NMEA 2000 Interface

The Maretron CLMD12 is a versatile and compact 12-channel DC load controller designed for vessels requiring precise load management. This module features twelve electronic circuit breakers, with two capable of handling up to 12 amps, six supporting up to 10 amps, and four managing up to 5 amps, providing a total current capacity of 75 amps. Each breaker can be individually set to trip at lower current levels through Maretron's N2KAnalyzerV3 software, offering tailored protection for various circuits. The CLMD12 also includes inputs for up to seven hard-wired switches that can control breaker states or serve as data inputs for system monitoring, such as bilge alarms or hatch positions. This flexibility enables integration with a range of vessel systems for enhanced control and safety.

Designed with marine environment durability in mind, the CLMD12 is IP67 rated for water and dust resistance and is ignition protected, making it suitable for demanding conditions. Its NMEA 2000 interface ensures seamless communication with other marine electronics, and the opto-isolation from the NMEA network prevents ground loop issues. The module provides real-time current monitoring for each breaker, allowing operators to identify overcurrent faults or undercurrent conditions like burnt-out bulbs quickly. For manual load control, an optional MPower 12-Channel Bypass Module (CBMD12) can be added, offering direct control over connected loads.

Ideal applications include remote control of navigation and boarding lights, alerting for burnt-out bulbs, and controlling area lighting with dimming capabilities. The CLMD12's ability to lock breakers against inadvertent actuation and configure power-up states enhances operational safety and customization. This product is engineered to support the electrical management needs of vessels of all sizes, providing reliable, integrated control over multiple DC loads while ensuring system monitoring and protection are maintained efficiently.
