POWER CONNECTOR (W)
The MTU-AIS requires a DC power supply with a rated voltage of 12VDC or 24VDC and can
operate in a voltage range between 10V and 32VDC.
The current peak when output at 12V is 3A.
The total average consumption will depend on the configuration used and the messages
transmitted periodically.
IMPORTANT NOTICE
The GPS antenna must be active type with 3.3V and must be electrically isolated from the VHF radio
connector otherwise it may cause damage to the AIS
