AC/DC Adapter Specs for S12 and T20: Two different power cords

Updated by Hayden Everly on Mar 1, 2023

In JUNE 2009, Plantronics made a change to the DCA power cord for S12 and T20 bases. This is important to know because they are not interchangeable. Plantronics changed the S12/T20 DCA and its connection on the base. This means that:

- Old DCA’s will not fit New S12/S11/S10/T20 bases

- New DCA’s will not fit Old S12/S11/S10/T20 bases

In order to make sure you get the correct DCA for the S12/S11/S10/T20 the Customer has, It is extremely important to check the part number on the plug you currently have for your base. (If DCA is missing, check date code underneath base)
