Maretron CBMD12 12-Circuit NMEA 2000 Bypass Module with Manual Control and Overcurrent Protection

12 Circuit Bypass Module NMEA 2K without Fuse Pack Jumper Wire

For manual control of the loads, an optional MPower 12-Channel Bypass Module (CBMD12) can be installed in conjunction with the 12-Channel DC Load Controller Module (CLMD12). The maximum current capacity for the CBMD12 is 75 amps in 12V DC and 24V DC power systems.

The Bypass Module provides a manual method (ON/OFF switch) to control loads by providing power to each load in case of a CLMD12 malfunction or a NMEA 2000 network failure. The CBMD12 utilizes standard fuses for overcurrent protection and 12 Carling Curvette Rocker Switches for manual control of each load. With the use of the Curvette rocker switches, there is no arcing that occurs while manually overriding a load. Furthermore, unlike other digital switching products, MPower does not require moving a fuse, which can cause electrical connections to degrade or the possibility of ignition.

Its important to ensure that the current rating of the fuse for each load is appropriate to protect the load and the wiring for that load. Please note that the bypass module does not support paralleled outputs, since each circuit is controlled by a separate switch. Additionally, the bypass module does not support dimming of circuits.

The Maretron CBMD12 12-Circuit Bypass Module offers a reliable manual control solution for marine and industrial electrical systems. Designed to work seamlessly with the Maretron NMEA 2000 network, this module provides a straightforward method to override load controls in case of system malfunctions or network failures. With a maximum current capacity of 75 amps, it supports a variety of power systems operating at 12V or 24V DC, making it suitable for a wide range of applications. Each of the twelve outputs is independently controlled via Carling Curvette Rocker Switches, which facilitate safe manual operation without arcing, ensuring durability and safety during load overrides. The module's overcurrent protection is provided by standard ATC fuses, allowing users to select appropriate fuse ratings to safeguard connected loads and wiring. This feature is essential for maintaining system integrity and preventing damage from electrical surges.

The CBMD12 is designed for easy installation and operation, with no support for paralleled outputs or circuit dimming, focusing on straightforward load control and safety. It includes two outputs with a maximum of 12 amps each, six outputs rated up to 10 amps, and four outputs rated up to 5 amps, accommodating a broad spectrum of load requirements. The robust construction and use of high-quality components ensure long-term reliability in demanding environments.
