[SIGLOCH RAINER DIPL ING, WOELFEL WERNER DIPL ING] DE In the case of known electrical power supply units for telecommunications devices, the transformer and the inductor are plugged onto the printed circuit board as separate components and are soldered to it. In this case, the transformer cannot be connected to the inductor via the printed circuit board, and the two components must be connected to one another by means of free wiring. This makes the production of the unit costly and, in addition, the electromagnetic compatibility is poor, because of the free wiring. The problem which is to be solved comprises the simplification of the production of the electrical power supply unit and improvement of the electromagnetic compatibility. The basic idea of the invention is to accommodate the transformer 40, the inductor coil 32 and the leads 42 connecting them together in a common housing 44 and to pot this assembly using a plastic compound 45, all the external connecting pins 2 to 27 being passed out of one surface 46 of the housing 44. In this way, the number of components and the number of exits from the housing are reduced. In addition, the wiring of the electrical power supply unit is simplified. <IMAGE>
