The AC1352 is a 6-pin female optional connector mates with the power connector, P3, on the 3B01, 3B02, 3B03 backplanes, to supply regulated ±15 V DC and +24 V DC power to the backplanes. Using the AC1352 connector to bring external regulated power to a 3B Series backplane eliminates the need for an on-board AC/DC or DC/DC converter.
