    Threshold tolerances and hysteresis:
    If
    Ui is monitored, the internal input voltage is measured af-
    ter the input filter and rectifier. Consequently this voltage
    differs from the voltage at the connector pins by the voltage
    drop
    DUti across input filter and rectifier. The threshold level
    of option V0 is adjusted during manufacture at
    Io nom and TA
    = 25
    °C. The value of DU
    ti depends upon the threshold level
    Ut, temperature and input current. The input current is a
    function of input voltage and output power.
    1 VME request: minimum 4 ms
    2 tlow min = 40...200 ms, typically 80 ms
    3 UV level not defined at Uo1 < 2.0 V
    4 The V signal drops simultaneously with the output voltage. If the
    pull-up resistor
    RP is connected to Vo1+. The V signal remains
    high if
    RP is connected to an external source.
