Q-Series
24V, 40A, SINGLE PHASE INPUT
Switching Frequencies
The power supply has four converters with four different switching frequencies included.
One is nearly constant. The others are input voltage and load dependent.
Switching frequency 1 105kHz Resonant converter, nearly constant
Switching frequency 2 1kHz to 150kHz Boost converter, input voltage and load dependent
Switching frequency 3 1kHz to 100kHz PFC converter, input voltage and load dependent
Switching frequency 4 25kHz to 45kHz Aux. 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 or surrounding temperature and is defined as the air temperature 2cm below the
unit.
**) Do not energize while condensation is present.
***) Higher levels allowed when using the wall mounting bracket ZM2.WALL
