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.
