Maretron MPower 12 Channel DC Load Controller Module w/NMEA 2K – No Connectors

The Maretron MPower CLMD12 is a 12-channel NMEA 2000 DC load controller for networked digital switching on a boat. It is a compact black-box module with no display, charting, sonar, or wireless connection. The unit is designed to control and monitor DC circuits through Maretron N2KView or a compatible NMEA 2000 control system.

The twelve electronic circuit breakers are arranged for different load sizes: four 5A, six 10A, and two 12A channels, with 75A total capacity. That makes the channel plan important before installation; a pump or lighting circuit must be connected to a channel within its rating. The module accepts 6.5-32V DC, is ignition protected, and carries an IP67 rating for surface mounting. Connectors are not included in this version, so the wiring parts must be planned separately.

Who Is This For?

This digital DC load controller suits boat owners building a Maretron NMEA 2000 switching system for lights, pumps, and other accessories. It is not a display or conventional chartplotter, and the no-connectors version requires the installer to source and terminate the wiring separately.

Warranty & Support

Maretron provides a 1-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The CLMD12 is the smaller Maretron switching option for a boat that needs twelve controlled DC circuits rather than the higher 16-channel capacity of the CLMD16. The trade-off is limited capacity and the absence of connectors in this package. Choose it when the channel ratings match the load plan and the boat already has a compatible NMEA 2000 control system.
