Detailed description
Detailed description
Designed for vessels of any size requiring optimized management of low loads, the DC load control module Maretron CLMD12 is a component of the MPower® digital switching platform. It integrates 12 dimmable electronic circuit breakers (ECBs) (PWM) for ON/OFF control via the NMEA 2000 network.
Load capacity and monitoring
Of the 12 circuit breakers, 2 handle a maximum current of 12 amperes, 6 a maximum of 10 amperes, and 4 a maximum of 5 amperes, for a total current capacity of 75 amperes. Similar circuits can be paralleled. Each circuit breaker provides individual electrical current monitoring, enabling detection of overcurrents and undercurrents. This information is essential for diagnosing and maintaining embedded systems.
Connectivity and system integration
The CLMD12 connects directly to the NMEA 2000® network, ensuring compatibility with a variety of sensors, instruments, and third-party multifunction displays (MFDs) supporting standard digital switching PGNs, including Raymarine LightHouse 4 systems. It is also compatible with Maretron TSM Series touchscreens, MPower VMM6 digital switch modules, and MPower CKM12 keypads. The module features 7 discrete inputs, configurable as active-high or active-low inputs, for wired switches or external sensors such as bilge alarms or panel positions.
Advanced features and robustness
This module is rated IP67 and is ignition-protected, making it suitable for demanding marine environments. It is opto-isolated from the NMEA 2000 network, eliminating potential ground loops. Circuit breakers can be configured with defined power-on states (ON, OFF, or last state) and can be locked against accidental activation. The Maretron CLMD12 includes automatic overcurrent protection (ECB shutdown) and overtemperature protection (thermal shutdown). It can be used to manage various types of DC loads such as lighting, pumps, motors, and electronics, offering advanced control and automation capabilities.
