    Threshold tolerances and hysteresis:
    If
    Ui is monitored, the internal input voltage is measured af-
    ter the input filter and rectifier (EM, LM and LMZ types).
    Consequently this voltage differs from the voltage at the
    connector pins by the voltage drop
    U
    t i across input filter
    and rectifier. The threshold level of option V0 is factory ad-
    justed at
    Io nom and TA = 25
    °C. The value of U
    t i depends
    upon the input voltage range (AM, BM, ...), threshold level
    Ut i, temperature and input current. The input current is a
    function of input voltage and output power.

    pull-up resistor
    RP is connected to Vo1+. The V signal remains
    high if
    RP is connected to an external source.
