Input voltage monitoring
Output voltage monitoring
Threshold tolerances and hysteresis:
If
Ui is monitored, the internal input voltage is measured af-
ter the input filter and rectifier (E/LM and LMZ types). Con-
sequently this voltage differs from the voltage at the con-
nector pins by the voltage drop
U
t i across input filter and
rectifier. The threshold level of option V0 is factory adjusted
at
Io nom and TA = 25
°C.The value of Ut i depends upon the
input voltage range (AM, BM, ...), threshold level
U ti, tem-
perature and input current. The input current is a function of
input voltage and output power.

Relationship between Ui, Uo1, UV, IV and Uo1/Uo nom versus time.
1 VME request: minimum 4 ms
2 t low 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.
