  • Totally insulated switched mode power supply
    Patent number: 8913355
    Abstract: A totally insulated switched mode power supply for producing a supply voltage for an electrical device, wherein the switched mode power supply includes a first and a second electrical conductor, of which one electrical conductor is for connection to a phase conductor and the other electrical conductor is for connection to a neutral conductor of a grounded AC or three-phase power supply system, and includes Y capacitors for asymmetrical interference suppression of the switched mode power supply such that measures are provided for reducing fault currents or leakage currents.
    Type: Grant
    Filed: August 7, 2012
    Date of Patent: December 16, 2014
    Assignee: Siemens Aktiengesellschaft

  • System unit for a computer
    Patent number: 8392033
    Abstract: A system unit for a computer comprising at least one plug-in card provided with components and a ventilator for cooling the components, wherein the system unit is also provided with a controller for setting the ventilator speed as a function of a signal of a temperature sensor. Measures are provided which, irrespective of whether the system unit is integrated in a horizontal or vertical position, such as in a switchgear cabinet, effect a good level of cooling.
