*)
Radiated emission EN 55011, EN 55022 Class A
*) There are no mandatory requirements in the generic standard EN 61000-6-4 for conducted emission on DC lines (input and
output). For the assessment of the conducted emission, the input filter of the frequency converter or servo amplifier need to be
taken into account.
Switching Frequencies
The power supply has three converters with three different switching frequencies
included. One is nearly constant. The other two are input voltage and load dependent.
Switching frequency 1 100kHz Nearly constant
Switching frequency 2 30kHz to 90kHz Input voltage and load dependent
Switching frequency 3 17kHz to 120kHz Input voltage and load dependent
