Input voltage monitoring
Output voltage monitoring
Threshold tolerances and hysteresis:
If
Ui is monitored, the internal input voltage after the input
filter and rectifier is measured. Consequently this voltage
differs from the voltage at the connector pins by the voltage
drop
U
ti across the input filter. The value of Uti depends
upon the input voltage range, threshold level
Ut, tempera-
ture and input current. The input current is a function of the
input voltage and the output power.
