    • The present disclosure relates to a power supply unit having: an output for outputting an output current and an output voltage; and a protective element having a signal output path, wherein the protective element is connected downstream of the output and designed to maintain the signal output path when the output current exceeds a first amplitude threshold value and to interrupt the signal output path when the output current exceeds a second amplitude threshold value, the second amplitude threshold value being higher than the first amplitude threshold value; wherein the power supply unit is designed to reduce an amplitude of the output voltage and to increase an amplitude of the output current above the second amplitude threshold value, in order to interrupt the signal output path, when the output current exceeds the first amplitude threshold value.
    • 本公开涉及一种电源单元,具有:用于输出输出电流和输出电压的输出; 以及具有信号输出路径的保护元件,其中所述保护元件连接在所述输出端的下游,并被设计为当所述输出电流超过第一幅度阈值时保持所述信号输出路径,并且当所述输出电流超过所述输出电流时中断所述信号输出路径 第二幅度阈值,所述第二幅度阈值高于所述第一幅度阈值; 其中所述电源单元被设计成当所述输出电流超过所述第一振幅阈值时,为了中断所述信号输出路径,设计为减小所述输出电压的幅度并增加所述输出电流的幅度高于所述第二幅度阈值 。
