Know before you buy
Yes, the CLMD12 supports remote dimming for compatible DC lighting circuits. You can manage these settings directly through your NMEA 2000 network display.
The module is designed to maintain its last known state. For critical systems, we recommend installing the optional manual bypass module, which allows you to override the digital control and operate your loads manually.
The module monitors current draw on each individual circuit. If a bulb fails, the resulting drop in current is detected, and the system reports the fault condition to your NMEA 2000-compatible display.
Yes, the breaker trip points are fully customizable. You can configure each channel to match the specific current requirements of your pumps, lights, or electronics via the NMEA 2000 interface.
Yes, the CLMD12 is ignition protected and IP67 rated, meaning it is sealed against dust and water immersion. This makes it suitable for installation in harsh environments, including engine rooms.
The unit has a total current capacity of 75 Amps. It features a specific breaker configuration consisting of two 12A channels, six 10A channels, and four 5A channels.
