Input voltage monitoring
Output voltage monitoring
11008
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.
