A dual line active automatic transfer switch (ATS) is provided. A first switch structure is connected to a first PSU of the plurality of PSUs, and operable between a first position connecting a first input line of the dual line and a second position connecting a second input line of the dual line with the one PSU. A second switch structure is connected to at least one additional PSU of the plurality of PSUs, and operable between a third position connecting the first input line and a fourth position connecting the second input line with the at least one additional PSU. The first and second switch structures are operable between each of the first, second, third, and fourth positions to alternatively connect each of the plurality of PSUs to one of the first and second input lines and connect, when each of the dual lines is charged, both of the first and second input lines to at least one of the plurality of PSUs.
