Maretron MPower CLMD16 16-Channel DC Load Controller Module with NMEA 2000 Interface and J1 & J2 Connectors

MPower 16-Channel DC Load Controller Module with NMEA 2K with J1 J2 Connectors

For larger breakers and more circuits, the MPower CLMD16 is a 16-Channel DC Load Controller Module. Four of the 16 breakers handle a maximum of 25 amps, and twelve breakers handle a maximum of 12 amps, with a total current capacity of 125 Amps. Additionally, circuits can be paralleled.

The CLMD16 also supports two H-Bridge reversing polarity circuits that can be used for loads such as engine hatches, passerelles, trim tabs, etc. The CLMD16 has 8 inputs for 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. There are 3 inputs capable of monitoring tank levels.

The CLMD16 handles many DC load types such as lights, pumps, motors, and electronics. An added benefit of the CLMD16 is that it reports the current through each of the 16 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.
