Abstract:
1. A method for operating an air-cooled switched-mode power supply unit for industrial use, comprising: providing a switched-mode power supply unit comprising heat-emitting switching elements; providing at least two thermocouples disposed in the switched-mode power supply unit at different measuring points to measure temperatures; measuring temperatures, by the at least two thermocouples, influenced by the heat-emitting switching elements; transmitting measured temperature data from the at least two thermocouples to a control unit; comparing the measured temperature data with temperature patterns stored in the control unit, and controlling, by the control unit, the switched-mode power supply unit as a function of a selected temperature pattern, wherein the selected temperature pattern corresponds to the measured temperature data, and wherein the power supply unit adjusts transferred powers to a power network according to the selected temperature pattern.
