Conducted emission
input lines
EN 55011, EN 55022, FCC Part 15, CISPR 11, CISPR 22 15dB higher than average limits
for DC power port according to
EN 61000-6-4
*)
Conducted emission
output lines
IEC/CISPR 16-1-2, IEC/CISPR 16-2-1 5dB higher than average limits
for DC power port according to
EN 61000-6-4

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
Oct. 2016 / Rev. 2.0 DS-QTD20.241-EN
All parameters are specified at 24V, 20A, 600Vdc input, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
