    Test Sockets (Main output only )
    Test sockets for measuring the output voltage
    Uo1 are lo-
    cated at the front of the module. The positive test socket is
    protected by a series resistor (see:
    Functional Description,
    block diagrams). The voltage measured at the test sockets
    is approximately 30 mV lower than the value measured at
    the output terminals.
    In case of double output units externally connected in se-
    ries for
    Uo = 24 V, 30 V or 48 V the monitored output volt-
    age is 12 V, 15 V or 24 V respectively.
