Abstract:
1. An electrical device that is connectable via a mains plug ( 65 ) to a mains voltage ( 7 ) and that has a stand-by mode or an energy saving mode the electrical device comprising an interference suppression capacitor circuit ( 96 ), made up of at least one interference suppression capacitor ( 6 , 60 ), a power supply unit ( 2 ) and a control unit ( 3 ) for the stand-by mode or the energy saving mode, a monitor for detecting the mains voltage, so as to detect, at least in the stand-by mode or energy saving mode, an interruption to the mains voltage ( 7 ) and has an active switching element ( 68 ) with which an electrical load ( 69 ; 5 , 8 ) can be connected in parallel to the at least one interference suppression capacitor ( 6 ), so that the at least one interference suppression capacitor ( 6 ) is actively discharged when an interruption to the mains voltage ( 7 ) has been detected and the power supply unit ( 2 ) has a power factor correction circuit ( 5 ) and a DC/DC converter ( 8 ) and the electrical load forms at least one part of at least one of the power factor correction circuit ( 5 ) or at least one part of the DC/DC converter ( 8 ).
