Powering the NMEA 2000 network
The network requires its own 12 V DC power supply, protected by a
3 A fuse.
For smaller systems: connect power at any location in the backbone.
For larger systems: connect power at a central point in the
backbone to balance the voltage drop of the network. Make the
installation such that the load/current draw on each side of the
power node is equal.
Ú
Note:
1 LEN (Load Equivalency Number) equals 50 mA current
draw.
