        Input Fuse
        A fuse mounted inside the converter protects the module
        against severe defects. If operated from a DC source this
        fuse may not fully protect the module when the input volt-
        age exceeds 200 V DC! In applications where the convert-
        ers operate at source voltages above 200 V DC an external
        fuse or a circuit breaker at system 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).
        Reverse Polarity Protection
        The built-in bridge rectifier provides reverse polarity protec-
        tion at the input.
        Inrush Current Limitation
        The modules of the versions -7 incorporate an NTC resistor
        in the input circuitry which – at initial turn on – reduces the
        peak inrush current value by a factor of 5...10 to protect
        connectors and switching devices from damage. Subse-
        quent switch-on cycles within short periods will cause an
        increase of the peak inrush current value due to the warm-
        ing-up of the NTC resistor. (see also:
        option E)
        Inrush Current Peak Value
        The inrush current peak value (initial switch-on cycle) can
        be determined by following calculation: (See also:
        Input In-
        rush Current Characteristic).

        AC frequency range 47...440 Hz (440 Hz
        for 115 V mains).
        Above 70 Hz (at
        Ui = 264 V AC) the earth
        lekage current may exceed 3.5 mA, speci-
        fied in IEC/EN 60950. The built-in Y ca-
        pacitors are specified for
        ≤100 Hz. Above
        350 Hz the input voltage may not exceed
        200 V AC.
