      Threshold tolerances and hysteresis:
      If
      Ui is monitored, the internal input voltage after the input
      filter is measured. Consequently this voltage differs from
      the voltage at the connector pins by the voltage drop
      DUti
      across the input filter. The threshold levels of the D0 and D9
      options are factory adjusted at nominal output current
      Io nom
      and at
      TA = 25
      °C. The value of DU
      ti depends upon the input
      voltage range (CK, DK, ..), threshold level
      Ut, temperature
      and input current. The input current is a function of the input
      voltage and the output power.
