Multi-functional operating device for supplying a consumer, such as an LED module and method for its operation

The invention relates to a method for supplying at least one consumer as an LED module and an energy storage device, in which a-supplied by an input circuit DC link at least supplies two output stages, wherein the consumer is connected to a first output stage and the energy store to a second output stage. The inventive method is characterized in that the second output stage is placed in different operating states, said load in an operating state of the second output stage of the power storage from the intermediate circuit and is supplied in a different operating state of the second output stage of the DC link from the energy storage. The invention further relates to an operating device that operates with such a method.
