QT40.241
Q-Series
24V, 40A, THREE PHASE INPUT
Switching Frequencies
The power supply has three converters with three different switching frequencies
included. One is nearly constant. The others are variable.
Switching frequency 1 105kHz Resonant converter, nearly constant
Switching frequency 2 1kHz to 150kHz Boost converter, load dependent
Switching frequency 3 40kHz to 300kHz PFC converter, input voltage and load dependent

Operational temperature
*)
-25°C to +70°C (-13°F to 158°F) reduce output power according Fig. 18-1
Storage temperature -40 to +85°C (-40°F to 185°F) for storage and transportation
Output de-rating 24W/°C 60-70°C (140°F to 158°F)
Humidity

Altitude 0 to 2000m (0 to 6 560ft) without any restrictions
2000 to 6000m (6 560 to 20 000ft) reduce output power or ambient temperature,
see Fig. 18-2
IEC 62103, EN 50178, overvoltage category II
Altitude de-rating 60W/1000m or 5°C/1000m > 2000m (6500ft), see Fig. 18-2
Over-voltage category III IEC 62103, EN 50178, altitudes up to 2000m
II altitudes from 2000m to 6000m
Degree of pollution 2 IEC 62103, EN 50178, not conductive
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 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 26.4.
**) Do not energize while condensation is present.
***) Higher levels allowed when using the wall mounting bracket ZM2.WALL
