Description

AMEC - B650S - AIS Class B+ 5W SOTDMA Transponder with VHF Splitter

The B650S is a 5 W Class B+ AIS transponder that uses SOTDMA technology. Unlike a 2-W Class B CSTDMA AIS, it transmits at a higher power and reserves its transmission slots AIS, which improves transmission consistency in high-traffic areas.

It features AMEC’s third-generation AIS engine, with a reception sensitivity of -111 dBm, a 72-channel GNSS receiver compatible with GPS, Galileo, GLONASS, and BeiDou, as well as an IP68-rated housing. It connects easily to onboard electronics via NMEA 2000, NMEA 0183, and USB---C interfaces.

Integrated VHF Splitter

With SOTDMA, the B650S reserves its transmission slots AIS in advance. Messages are sent more consistently, especially when many vessels are transmitting at the same time. Its 5 W power output also gives it a greater range than AIS Class B 2 W transponders.

  • Transmission AIS 5 W Class B+ SOTDMA
  • -Receive Sensitivity: 111 dBm
  • 72-channel GNSS receiver
  • Built-in VHF splitter to simplify installation

This AIS transponder is suitable for recreational boating, coastal cruising, offshore navigation, and areas with heavy maritime traffic.


Connection to onboard electronics

The B650S features NMEA 2000, NMEA 0183, and USB--C connections. Its NMEA 0183 multiplexing function allows data to be redistributed to NMEA 0183, USB, and Wi--Fi outputs, depending on the version.

  • 12 V or 24 V DC power supply
  • Average current draw: 120 mA at 12 V
  • Peak current: 1.7 A at 12 V
  • Weight: 400 grams

Its compact design makes installation easy. Status LEDs allow for quick monitoring of operation, while the IP68-rated housing protects the device on board.
