Answer
The newer, Revision 2 ConnexLink units ship with the Channel Well Technology power adapter, Part Number: E99-AEA12FA-A023. This is a 12W, 1A power adapter. Ezurio does not sell power adapters separately.
Any adapter within the supply voltage limits specified in the Datasheet for the ConnexLink CL4490 or CL4790 can be used as a replacement adapter. Note: The Max Power settings to set the TX power of the units to Max, Half, Quarter and Low settings are based on a 12 V DC input voltage as indicated in the datasheets.
For the barrel measurements please see images below:
Older, Revision 1 Hardware ConnexLink units shipped with a 7.5W, 1.5A power adapter, with the same barrel measurements indicated above. We no longer sell the power adapter for these units separately. If you have an older unit and need to replace the power supply, we still recommend getting a power adapter that supports 7.5W-1.5A.
