Does the NBF-3 need external power?

Yes, the NBF-3 requires a supply between 10 to 35V DC and will use a maximum of 100mA at 12V DC (when all outputs are fully loaded with 100?). This does not include the current draw of the NBF-3 ‘Power Output’ that can be used to power an NMEA Talker device up to an additional 500mA.
