Input voltage monitoring
Output voltage monitoring
Threshold tolerances and hysteresis:
If
Ui is monitored, the internal input voltage after the input
filter and rectifier (E/LM and LMZ types) is measured. Con-
sequently this voltage differs from the voltage at the con-
nector pins by the voltage drop
U
ti across input filter and
rectifier. The threshold level of the D0 and D9 options is fac-
tory adjusted at nominal output current
Io nom and at TA =
25
°C. The value of Uti 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.

1 See "El. output data", for hold-up time.
2 With output voltage monitoring the hold-up time th = 0
3 The D signal remains high if the D output is connected to
an external source.
