Abstract
A circuit arrangement for feeding a module requiring a constant operating voltage in a user station fed by a current-conducting connection path, composed of: components defining a current control unit connected for controlling the current in the connection path; components defining a resistance control unit connected for controlling the alternating current resistance presented by the circuit arrangement to the connection path; a first current conducting branch connected for feeding current supplied by the connection path to the module; a second current conducting branch connected for conducting current supplied by the connection path in a manner to bypass the module; and a signal responsive switch connected for establishing current flow between the connection path and a selected one of the branches.
