Used in various electronics that include cameras and computers, a DC coupler serves a basic function for the tech-savvy user. Primarily built for convenience, DC couplers also can increase the efficiency of electronic operations.


The basic definition of a DC coupler, or conductive coupler, is a cord which a basic branch that splits to form two circuits or channels. When used in electronics and mechanical tasks, a DC coupler often is used to isolate power and telecommunication circuits.


Unlike AC coupling, DC coupling allows both AC and DC circuits to pass through. In AC coupling, only AC signals are accepted and the DC signal is entirely removed.


Several companies offer DC couplers for personal and commercial use. These companies include Fujifilm, Canon, Olympus and Panasonic.
