Table 7.1 General Technical Data
1) The fan control system supports extended input voltage range as 200–415 V for the 380 V/60 Hz and 400 V/50 Hz programs. The 380 V/60 Hz
and the 400 V/50 Hz programs can be operated with 200–240 V mains supply.
2) THDi level is system level performance from the filter combined with the actual frequency converter.
NOTICE
The reduction of the low harmonic current emission to the rated THDi implies that the THDv of the non-influenced
mains voltage is lower than 2%, and the ratio of short circuit power to installed load (R
SCE
) is above 66. Under these
conditions, the THDi of the mains current of the frequency converter is reduced to 10% or 5% (typical values at nominal
load). If these conditions are not or only partially fulfilled, a significant reduction of the harmonic components can still
be achieved, but the rated THDi values may not be observed.
