QT20.241 Datasheet, PDF (14/27 Pages) PULS GmbH – THREE PHASE INPUT

Q-Series
QT20.241, QT20.241-C1
24V, 20A, THREE PHASE INPUT
Switching Frequencies
Switching frequency 1
Switching frequency 2
Switching frequency 3
The power supply has three converters with three different switching frequencies
included. One is nearly constant. The others are input voltage and load dependent.
100kHz
Resonant converter, nearly constant
30kHz to 90kHz
Boost converter, load dependent
40kHz to 220kHz PFC converter, input voltage and load dependent

LABS compatibility
The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
*) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2cm below the
unit. Curves and figures for operation on only 2 legs of a 3-phase system can be found in chapter 22.4.
**) Do not energize while condensation is present.
