Maretron MPower CLMD12 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 is a compact and versatile 12-channel DC load controller designed for vessel applications requiring reliable power management. Suitable for small loads, this module features a total current capacity of 75 amps, with specific breakers rated for different load levels, including two breakers handling up to 12 amps, six breakers up to 10 amps, and four breakers up to 5 amps. The design allows for circuits to be paralleled, providing flexibility for various electrical configurations. Each of the 12 electronic circuit breakers (ECBs) can be set to trip at lower current thresholds using Maretron's N2KAnalyzerV3 software, enabling precise circuit protection tailored to your needs. The CLMD12 supports up to seven hard-wired inputs, which can be used to switch breaker states or to monitor systems like bilge alarms or hatch positions, enhancing vessel safety and automation. This module is compatible with many DC loads such as lighting, pumps, motors, and electronics, and it offers real-time current reporting for each breaker, allowing for proactive management of electrical loads and fault detection. An optional MPower 12-Channel Bypass Module (CBMD12) can be added for manual load control, providing additional operational flexibility. The CLMD12 is IP67 rated for water resistance and is ignition protected, making it suitable for marine environments. Its features include opto-isolation from NMEA 2000 to prevent ground loops, individual breaker current monitoring, configurable power-up states, lockable breakers, and automatic overcurrent and thermal shutdown protections. This module is ideal for remote control of navigation and area lighting, monitoring for burnt-out bulbs, and controlling lighting with dimming capabilities, supporting enhanced vessel automation and safety. Designed for easy integration into NMEA 2000 networks, the Maretron CLMD12 offers reliable load management with advanced monitoring and control features to optimize vessel electrical systems.
