Patent number: 10520962Abstract: The present invention relates to a supply voltage detection device (1), in particular for at least one load, for monitoring a rectified mains voltage of a mains voltage supply (2) and for comparing a detected mains voltage value with a predetermined reference value, wherein, if the detected mains voltage value is lower than the reference value, switching to e.g. an emergency voltage of an emergency voltage supply can be effected by means of an electronic control system (3). In addition, if a voltage limit value has been exceeded, the rectified mains voltage can be fed to an optocoupler (4) and a signal can be transmitted by said optocoupler for the duration of this excess, a duty factor that is dependent on the mains voltage value being determinable from the duration and the period of said signal.Type: GrantFiled: August 21, 2015Date of Patent: December 31, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventor: Johannes Frucht

Patent number: 8018179Abstract: An apparatus for monitoring at least one fluorescent lamp, in particular in an explosion-hazard area, which fluorescent lamp has a lamp tube with electrodes arranged at its ends in the form of filaments, and has a ballast, is improved in order to avoid an excessive temperature increase while maintaining the appropriate explosion protection in that the monitoring apparatus has at least one temperature measurement device, associated with a filament, and an electronic interruption device, by means of which interruption device the power supply can be interrupted by means of the ballast on reaching a predetermined critical temperature. The invention likewise relates to a corresponding method for monitoring at least one fluorescent lamp, in particular in an explosion-hazard area. In this method, the temperature is first of all detected in the area of at least one filament of the fluorescent lamp.Type: GrantFiled: July 27, 2007Date of Patent: September 13, 2011Assignee: Cooper Crouse-Hinds GmbHInventor: Johannes Frucht

Patent number: 7723954Abstract: The invention relates to a method and a device for supplying at least one load consumer during a mains failure. According to said method, a plurality of batteries acts as an emergency voltage source during the failure of a mains voltage source in order to supply the load consumer(s). The plurality of batteries is connected to the mains voltage source. The batteries are interconnected in series in order to form the emergency supply for the load consumer. To permit a simple, cost-effective emergency supply with a reliable charging of the batteries, the plurality of series-connected batteries is sub-divided into at least two battery groups using a splitter circuit and each of said battery groups is connected to the mains voltage source for charging purposes by means of a corresponding connection circuit.Type: GrantFiled: March 29, 2004Date of Patent: May 25, 2010Assignee: Cooper Crouse-Hinds GmbHInventor: Johannes Frücht
