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

Description

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.

Key Features

• 12 electronic circuit breakers – Provides network-controlled switching for multiple DC loads.
• 5A, 10A, and 12A channel ratings – Lets the installer match each load to the correct circuit capacity.
• 75A total capacity – Defines the combined load limit for the controller.
• NMEA 2000 Micro-C and seven discrete inputs – Supports network control and the listed input connections.
• IP67 and ignition-protected housing – Suits protected surface mounting in a marine electrical installation.

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.

Compatibility

Confirmed compatibility includes NMEA 2000 CAN bus, one NMEA 2000 Micro-C connector, seven discrete inputs, Maretron N2KView, and N2KAnalyzer V3. The supplied information does not identify Garmin, Raymarine, Simrad, or other third-party control-display compatibility. No named incompatible system was provided; verify the network, connector, and load-circuit plan before installation.

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.
