The power adapter 11v13 is for use with the radio/power interface and radios which require a power supply less than eleven volts.
In particular, the adapter allows the interface to supply power to the later Icom A6 and A24 radios.
The adapter also includes a filter to suppress radio Frequency (RF) feedback (HIGH PITCHED SQUEAL) which can be a significant problem with these radios.
The adapter connects in -line between the power connector on the interface radio lead and the radio.
