      Input Under-/Overvoltage Lock-out
      If the input voltage remains below approx. 65 V AC or ex-
      ceeds approx. 280 V AC 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).
      Input Transient Protection
      A VDR together with the input fuse and a symmetrical input
      lter form an effective protection against high input tran-
      sient voltages.
      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 in-
      stalled!)

      2 Valid for -7, -6, versions with NTC, (-9 versions exclude the NTC). Initial switch-on cycle. Subsequent switch-on/off cycles increase the
      inrush current peak value.

      Reverse Polarity Protection
      Should the input voltage to the unit be supplied from a DC
      source the built-in bridge rectier provides reverse polarity
      protection.
      Inrush Current Limitation
      The modules of the versions -7, -6, incorporate an NTC re-
      sistor 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:
      E option.
      Inrush Current Peak Value
      The inrush current peak value (initial switch-on cycle) can
      be determined by following calculation:
