Input voltage monitoring
Output voltage monitoring

t
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.

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.
