    Input Fuse
    A fuse mounted inside the converter protects the module
    against severe defects. This fuse may not fully protect the
    module when the input voltage exceeds 200 V DC! In appli-
    cations where the converters operate at source voltages
    above 200 V DC an external fuse or a circuit breaker at sys-
    tem level should be installed!

    Input Under-/Overvoltage Lock-out
    If the input voltage remains below approx. 0.8
    Ui min or ex-
    ceeds approx. 1.1
    Ui max, an internally generated inhibit sig-
    nal disables the output(s). When checking this function the
    absolute maximum input voltage rating
    Ui abs should be
    considered! Between
    Ui min and the undervoltage lock-out
    level the output voltage may be below the value defined in
    table:
    Output data (see: Technical Information: Measuring
    and Testing).
    Hold-up Time versus relative Input Voltage
    Inrush Current Peak Value
    The inrush current peak value (initial switch-on cycle) can
    be determined by following calculation: (See also:

    Reverse Polarity
    The units are not protected against reverse polarity at the
    input to avoid unwanted power losses and may be dam-
