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.

Applications:
The Maretron CLMD12 is a compact and versatile 12-channel DC load controller designed for marine applications, providing reliable management for various electrical loads on vessels of all sizes. Its robust design incorporates twelve electronic circuit breakers (ECBs), with two capable of handling up to 12 amps, six rated for 10 amps, and four supporting 5 amps, offering a total current capacity of 75 amps. The module supports paralleled circuits, enabling flexible load management to suit different electrical demands. Each breaker can be individually configured to trip at lower current thresholds using Maretron's N2KAnalyzerV3 software, allowing tailored protection for smaller circuits or sensitive electronics.
The CLMD12 includes inputs for up to seven hard-wired switches, which can be used to control breaker states or serve as inputs for other data signals such as bilge alarms or hatch position indicators. This integration capability enhances vessel automation and safety. The module is compatible with various DC loads, including lighting, pumps, motors, and electronic devices, making it suitable for a wide range of onboard systems. Its ability to report the current draw of each breaker facilitates proactive maintenance by identifying overcurrent faults or undercurrent issues like burnt-out bulbs.
Designed for marine environments, the CLMD12 features an IP67 rating for water and dust resistance and is ignition protected to prevent sparks in hazardous areas. It is opto-isolated from the NMEA 2000 network, eliminating ground loop issues and ensuring signal integrity. The module supports configurable breaker power-up states—ON, OFF, or previous state—and allows breakers to be locked against inadvertent operation. For manual load control, an optional MPower 12-Channel Bypass Module (CBMD12) can be added. Overall, the CLMD12 provides a comprehensive solution for remote load management, circuit protection, and system monitoring, enhancing vessel safety and operational efficiency.
Whether managing navigation lights, controlling area lighting with dimming, or receiving alerts for burnt-out bulbs, the Maretron CLMD12 delivers precise control and monitoring capabilities. Its integration with NMEA 2000 networks ensures seamless communication with other marine electronics, making it a vital component for modern vessel electrical systems.
