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

MPower 12 Channel DC Load Controller Module with NMEA 2K - No Connectors

Designed for vessels of all sizes with smaller loads, the MPower CLMD12 is a compact 12-Channel DC Load Controller Module. Two of the 12 breakers handle a maximum of 12 amps, six handle a maximum of 10 amps, and four handle a maximum of 5 amps, with a total current capacity of 75 Amps. Additionally, circuits can be paralleled.

If a smaller circuit needs to be protected, each of the 12 breakers can be set to trip at lower current levels using the new Maretron N2KAnalyzerV3 software. In addition, the CLMD12 has inputs for up to 7 hard-wired switches that can be used to switch breaker states, or as inputs for other data, such as bilge alarms or hatch positions, etc.

The CLMD12 handles many DC load types such as lights, pumps, motors, and electronics. An added benefit of the CLMD12 is that it reports the current through each of the 12 breakers. This allows you to determine if loads are drawing too much or too little electrical current. This information can be used to report overcurrent faults and undercurrent conditions, such as burnt-out bulbs.

For manual control of the loads, an optional MPower 12-Channel Bypass Module (CBMD12) can be installed in conjunction with the CLMD12.

The Maretron CLMD12 MPower 12-Channel DC Load Controller Module is an advanced solution designed for vessels requiring reliable and flexible electrical load management. This compact, IP67-rated module connects seamlessly via NMEA 2000, providing a robust and marine-grade communication interface. It features twelve electronic circuit breakers (ECBs) with dimming capability, including two capable of handling up to 12 amps, six at 10 amps, and four at 5 amps, for a total current capacity of 75 amps. Each breaker can be individually set to trip at lower current levels using Maretron's N2KAnalyzerV3 software, offering tailored protection for various circuits. The module also supports parallel circuit configurations, enabling customization for complex electrical systems. An optional bypass module allows manual load control, providing additional flexibility for managing navigation, interior, or area lighting. The CLMD12 monitors the current draw of each circuit, enabling detection of overcurrent faults or undercurrent conditions such as burnt-out bulbs, thus enhancing safety and maintenance efficiency. Its design includes seven configurable inputs that can be used for switches, bilge alarms, hatch sensors, or other data sources, and breakers can be locked to prevent inadvertent operation. The module’s features include automatic overcurrent and thermal shutdown protections, making it suitable for controlling lights, pumps, motors, and electronics aboard marine vessels. Its ignition protection ensures safe operation in a variety of marine environments, while opto-isolation from NMEA 2000 prevents ground loops. This versatile component is ideal for remote control of navigation lights, boarding lights, and area lighting with dimming capabilities, providing a comprehensive solution for vessel electrical management needs.
