Series

Derating and mains voltage

Reduce overcurrent based on mains voltage.
Frequency Converter EFC x610 is thermally dimensioned for the rated current.
This rated current is available with the specified rated voltage. With deviating
voltages in the permissible range, please pay attention to the following:
U < U :
●
mains rated
With mains voltage below the rated voltage, no higher current may be with-
drawn to ensure that the dissipated power remains.
U > U :
●
mains rated
With mains voltage above the rated voltage, a reduction of the permissible
output permanent current takes place to compensate for the increased
switching losses.
