    Output Voltage Regulation of Double Output Modules
    Output 1 is under normal conditions regulated to
    Uo1 nom,
    independent of the output currents.
    Uo2 is dependent upon the load distribution. If both outputs
    are loaded with more than 10% of
    Io nom, the deviation of Uo2
    remains within
    ±5% of the value of U
    o1. The following 3
    gures 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 U
    o1 pro-
    vided that a total load of more than 10% of
    Io nom is applied.
    Two outputs of a single K 5000 module connected in paral-
    lel will behave like the output of a K 4000 module; the paral-
    leled output is fully regulated. No precautions are neces-
    sary in using the R-input and the test sockets.
