ABSTRACT The invention concerns a primary switched-mode power supply device with several electrically isolated secondary circuits, the output voltage of the secondary circuit being connected to an actual-value sensor with a regulator connected to the sensor output, with the output voltage being protected by a fuse connected in series with the filter capacitor. In accordance with the invention, the junction point of the filter capacitor and the fuse is connectable by an electrically controlled switch to the output terminal of the actual-value sensor as soon as the switch is turned on after the fuse has been tripped. Thus, a simple embodiment of an over-voltage protection is obtained for a primary switched-mode power supply unit with several electrically isolated secondary circuits, without additional monitoring of an in-phase output voltages A2 and A3 and a controlled secondary circuit being controlled in case of a fault to an output voltage that is lower than the normal operating controlled output voltage Al.
