Here is a short list of some popular NMEA-2000 products and their power load equivalency number or LEN. A unit of one LEN is equal to 0.050-Amperes or less of power consumed from the network, rounded up. A device that consumes 0.051-Ampere would be LEN =2. Information is taken from various manufacturer literature and from NMEA.ORG's website. The NMEA list is only for NMEA-2000 certified products.
EVINRUDE E-TEC
According to Evinrude's service manual literature, all E-TEC engines with a NMEA-2000 port on their EMM have a LEN of 1.
LOWRANCE
EP-series sensors = 1
LMF-200 = 4
LMF-400 = 4
SonicHub = 1
HDS series = 1
ICOM
The M506 radio has a LEN =1
GARMIN
Most models in the GPSmap series and most radios have a LEN = 2.
HONDA
Most Honda outboard engines have a LEN of 1 or 2. (See NMEA list for details.)
NAVICO
The Precision 9 compass has a LEN = 1.
RAYMARINE
Most Raymarine multi-function displays have a LEN = 1. (See NMEA list for details.)
SIMRAD
Most Simrad multi-function displays have a LEN = 1.
