    Threshold tolerances and hysteresis:
    If
    Ui is monitored, the internal input voltage after the input
    filter and rectifier (EM, LM and LMZ types) is measured.
    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 the D0 and D9 options is
    factory adjusted at nominal output current
    Io nom and at TA =
    25
    °C. The value of DU
    ti depends upon the input voltage
    range (AM, BM, ...), threshold level
    Ut, temperature and in-
    put current. The input current is a function of the input volt-
    age and the output power.
