Maretron MPower 12-Channel DC Load Module NMEA 2000 with 12-Inch Pigtail Adapter Cable - Part CLMD12-R

MPower 12 Channel DC Load Module NMEA 2K with 12 Pigtail Adapter Cable for J1 J2 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 N2KAnalyzer V3 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.

Features:

• NMEA 2000 Interface
• IP67 Rated
• Ignition Protected
• Opto-isolated from NMEA 2000, eliminating potential ground loops
• Twelve (12) dimmable Electronic Circuit Breakers (ECBs) for On/Off Control over NMEA 2000 network
• 2 breakers capable of carrying up to 12 Amps
• 6 breakers capable of carrying up to 10 Amps
• 4 breakers capable of carrying up to 5 Amps
• Individual breaker electrical current monitoring
• Breakers can have Power-Up states defined (ON, OFF, or PREVIOUS STATE)
• Breakers can be locked against inadvertent actuation.
• Seven (7) discrete inputs configurable as Active High or Active Low
• Automatic ECB overcurrent shutdown
• Automatic ECB thermal shutdown (Overtemperature Protection)

Applications:

• Remote control of navigation lights
• Remote control of the boarding lights
• Burnt-out bulb alerts
• Control of area lights with dimming

The Maretron CLMD12-R is a versatile 12-channel DC load controller designed for marine applications of all sizes. This compact module features twelve electronic circuit breakers capable of handling a combined current capacity of 75 amps. Two breakers support up to 12 amps each, six are rated for 10 amps, and four are rated for 5 amps, allowing for flexible load management. Each breaker can be set to trip at lower current levels through Maretron N2KAnalyzer V3 software, providing precise circuit protection tailored to specific needs. The CLMD12-R also includes inputs for up to seven hard-wired switches, which can be used to control breaker states or monitor data such as bilge alarms or hatch positions, enhancing vessel safety and automation.

Designed with marine durability in mind, the module is IP67 rated for water and dust resistance and is ignition protected, making it suitable for harsh environments. The NMEA 2000 interface ensures seamless integration with other marine electronics, and the opto-isolation feature prevents ground loop issues. The module reports real-time current draw for each breaker, enabling monitoring of loads like lights, pumps, motors, and electronics. This data can help identify overcurrent faults or undercurrent conditions, such as burnt-out bulbs, facilitating preventive maintenance.

For manual load control, an optional MPower 12-Channel Bypass Module can be installed alongside the CLMD12-R, providing additional flexibility. The breakers can be configured to have specific power-up states—ON, OFF, or previous state—and can be locked to prevent accidental actuation. Seven discrete inputs are configurable as active high or low, allowing integration with various sensors and alarms. Built-in safety features include automatic overcurrent and thermal shutdown protections, ensuring reliable operation in demanding marine environments.
