Maretron MPower CLMD16 16-Channel DC Load Controller Module with NMEA 2000 Interface

MPower 16-Channel DC Load Controller Module with NMEA 2K without 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.

The Maretron CLMD16 is a versatile 16-channel DC load controller designed for marine and industrial applications requiring reliable management of multiple circuits. Equipped with sixteen electronic circuit breakers, including four capable of handling up to 25 amps and twelve supporting up to 12 amps, this module offers a total current capacity of 125 amps. The CLMD16 supports circuit paralleling for expanded control flexibility and features two H-Bridge reversing polarity circuits suitable for loads such as engine hatches, passerelles, or trim tabs, enabling bidirectional control. Its design includes eight hard-wired switch inputs, which can be utilized to toggle breaker states or monitor other systems like bilge alarms and hatch positions. Additionally, three tank level inputs facilitate comprehensive monitoring of fluid levels, making this module suitable for complex marine systems. The CLMD16 not only manages loads such as lights, pumps, and motors but also reports the current draw for each breaker, aiding in diagnostics like overcurrent detection or identifying burnt-out bulbs. This real-time current monitoring ensures optimal electrical system performance and safety. The module's robust construction includes an IP67 rating for water and dust resistance, ignition protection, and opto-isolation from the NMEA 2000 network to prevent ground loop issues. Features like individual breaker lockout, configurable power-up states, and automatic overcurrent and thermal shutdown enhance operational safety. Local control is facilitated through capacitive touch switches, providing easy manual operation alongside digital network management. The CLMD16 supports multiple input types, including digital, resistive analog, and 4-20mA current loop inputs, offering versatile integration options for various sensors and control signals. This product is ideal for remote control of navigation and boarding lights, alerting for burnt-out bulbs, and dimmable area lighting, making it suitable for a wide array of marine power management needs.
