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.

It’s 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.

  • 75 Amps maximum current capacity

Works great for kids
Color: A-Navy Blue
Fits perfectly and allows my son to see the real color of his iPad. He is six and easily pops up the stand. It thinks it’s very cool. It is sturdy enough to protect against normal drops.

I’m really happy with this case. It fits my iPad perfectly, feels sturdy, and the clear back still shows off the design. The built-in screen protector and Apple Pencil holder are super convenient, and the stand works well for watching videos or typing. Overall, great quality for the price — highly recommend!

Get one!
Color: Peacock Blue, Color: Peacock Blue
Very nice IPad case. It fits really nicely. It took a while to get it setup because of how well it fits but it is well worth it. I love the he fact it uses magnets to position the screen instead of tracks. Stays in place while working instead of slipping throughout the day. I would and will recommend and buy again.
