Patent ID: 7959770

Claim:
Electrocoating plant for coating workpieces, comprising at least one immersion bath, in which at least one electrode is disposed, a conveying device, which brings the workpieces into the immersion bath and out of the immersion bath again, and a power supply device, which generates an output voltage from an a.c. input voltage, one output potential of which is applied to at least one of the workpieces to be coated and the other output potential of which is applied to at least one of the electrodes disposed in the immersion bath, wherein the power supply device comprises at least one current control unit which moves together with a workpiece associated with the current control unit through at least one section of the electrocoating plant and provides the output potential for the workpiece associated with the current control unit, wherein the power supply device comprises a first bus bar and a second bus bar to which the at least one current control unit can be connected, and wherein the first bus bar is earthed, and wherein the first bus bar and the second bus bar are associated with at least one immersion bath of the electrocoating plant and extends without electrical interruption over the length of the immersion bath.
