Abstract:
1. An electrical device comprising a power supply unit ( 2 ) that has a voltage converter ( 8 ) and an interference suppression capacitor circuit ( 96 ) made up of at least one interference suppression capacitor ( 6 , 60 ), and having a control unit ( 3 ) disposed on a primary side that has its own power supply circuit ( 10 ) directly connected to a mains voltage ( 7 ) and that can be controlled using an external signal ( 11 ), the electrical device ( 1 ) has an energy saving mode and the control unit ( 3 ) is configured to switch off the electrical energy on a secondary side of the power supply unit ( 2 ) when the electrical device ( 1 ) enters into the energy saving mode, the interference suppression capacitor circuit ( 96 ) is disposed on the primary side and the electrical device has at least one switch ( 62 ) to switch the interference suppression capacitor ( 6 , 60 ) on or off or to change an overall capacitance of the interference suppression capacitor circuit ( 96 ).
