摘要： A power supply unit comprises at least one first converter unit and a second converter unit. The at least one first converter unit is controlled with a first controller and supplies at a first output at least one of a first output voltage that is regulated using a first voltage regulator and an output current that is regulated using a first current regulator. The second converter unit is controlled by a second controller and supplies at a second output at least one of an output voltage that is regulated using the second voltage regulator and an output current that is regulated using a second current regulator. The first and second outputs are connected in parallel for providing a higher output power, and at least one controller includes a supervision unit for recognizing an output-side parallel connection.

摘要： Method for monitoring and controlling current distribution in load circuits of an installation control system of a technical installation, wherein a predetermined and constant output voltage is provided by a clocked power supply and distributed to the load circuits, where load circuits are protected by a switch actuated by a controller, a variation of the current in each load circuit is measured during a learning phase, a significant current profile with an associated tolerance range is derived and associated with the respective load circuit from the measured current variation which is continuously monitored by the control unit and a check is performed to determine whether a power capacity limit is reached by the clocked power supply while operate the installation, and the current consumed load circuits is reduced and/or switched off by actuating switches in load circuits in which a current variation exceeds an upper limit of the tolerance range.

摘要： A method for monitoring a power supply connected to a superordinate controller via a signal line, wherein the superordinate controller queries whether the power supply is operating faultlessly at variable intervals, where during faultless operation, a power-good signal is continuously transmitted by the power supply to the superordinate controller via the signal line and, if a fault occurs, an indicating signal is transmitted by the power supply to the superordinate controller via the signal line as a switching sequence of high and low signals such that each signal change of the switching sequence occurs only after a time period that is longer than an expected greatest query interval and each signal of the switching sequence that does not correspond to the power-good signal is shorter than a specified signal duration for indicating a total failure of the power supply, whereby the superordinate controller receives more information than previously.
