Radiated emission
EN 55011, EN 55022
Class A
This device complies with FCC Part 15 rules.
Operation is subjected to following two conditions: (1) this device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may cause undesired operation.
*)
There are no mandatory requirements in the generic standards EN 61000-6-4 and EN 61800-3 for conducted emissions on DC-Lines. For
assessment of the conducted emissions, the input filter of the frequency converter or servo amplifier need to be taken into account.
Switching Frequencies
The DC/DC converter has three converters with three different switching frequencies
included. One is nearly constant. The others are input voltage and load dependent.
Switching frequency 1
100kHz
Resonant converter, nearly constant
Switching frequency 2
30kHz to 90kHz
Boost converter, load dependent
Switching frequency 3
17kHz to 120kHz
Buck converter, input voltage and load dependent
