      Output Voltage Regulation of Single or Double Output
      Modules with Outputs 1 and 2 Connected in Series
      Output Voltage Regulation of Double Output Modules
      with Output 1 and 2 in Symmetrical Configuration
      Output 1 is under normal conditions regulated to
      Uo1 nom,
      independent of the output currents.
      Uo2 is dependent upon the load distribution. When both out-
      puts are loaded with more than 10% of
      Io nom, the deviation
      of
      Uo2 remains within ±5 % of the value of Uo1. The following
      3 figures show the regulation with varying load distribution.
      If
      Io1 = Io2 or the two outputs are connected in series, the de-
      viation of
      Uo2 remains within
      ±1% of the value of Uo1 pro-
      vided that a total load of more than 10% of
      Io nom is applied.
      Two outputs of a single K 2000 module connected in paral-
      lel will behave like the output of a K 1000 module; the paral-
      leled output is fully regulated. No precautions are neces-
      sary in using the R-input and the test sockets.
