  • Page 2 DL169-IN-B DL169-IN DL169-IN-B – The circuit Radiomodems DL169-IN-B and its open version DL169-IN are built by the interface and supply card RMO148 and the radiomodem module DL169. The RMO148 card realises the following functions: Power supply conditioning. A step-down switching regulator give a stabilised voltage of 5 Vdc from an input voltage between 8 to 36 Vdc.

  • Page 3: Note On Power Supply

    NOTE ON POWER SUPPLY The Radiomodem DL169 or DL169-IN-B should be fed with a power limited voltage source between 8 and 36 Vdc and is not re- quired a stabilisation due to the presence of an internal efficient stabiliser. The power supply is protected against polarity reversing and is protected by a 750 mA internal SMT fuse.
