The invention relates to a redundant module for decoupling short-circuit currents in a redundant voltage supply. The redundant module comprises at least two power supply units, and the number of inputs corresponds at least to the number of power supply units. Each input is routed via a separate current path to a common current node of an output for providing an output current. Each current path forms a decoupling section, and at least one measuring element for measuring the input voltage, the input current, and/or the input power as well as a control element for regulation purposes are assigned to each decoupling section.
