3-PHASE, 12V, 8A, 96W
15. ENVIRONMENT
Operational temperature -25°C to +70°C (-13°F to 158°F) The operational temperature is the ambient or
surrounding temperature and is defined as the
air temperature 2cm below the device.
Storage temperature -40°C to +85°C (-40°F to 185°F) For storage and transportation
Output de-rating 2.5W/°C
6W/1000m or 5°C/1000m
3.6W/-5kPa or 3°C/-5kPa
Between +60°C and +70°C (140°F to 158°F)
For altitudes >2000m (6560ft), see Fig. 15-2
For atmospheric pressures <80kPa, see Fig. 15-2
The de-rating is not hardware controlled. The customer has to take care by himself to
stay below the de-rated current limits in order not to overload the unit.
Humidity 5 to 95% r.h. According to IEC 60068-2-30
Atmospheric pressure 110-47kPa See Fig. 15-2 for details
Altitude Up to 6000m (20 000ft) See Fig. 15-2 for details
Over-voltage category III According to IEC 60664-1 for altitudes up to
2000m
II According to IEC 60664-1 for altitudes from
2000 to 6000m and atmospheric pressures
from 80 to 47kPa
Degree of pollution 2 According to IEC 62477-1, not conductive
Vibration sinusoidal 2-17.8Hz: ±1.6mm; 17.8-500Hz: 2g
2 hours / axis
According to IEC 60068-2-6
Shock 30g 6ms, 20g 11ms
3 bumps / direction, 18 bumps in total
According to IEC 60068-2-27
Shock and vibration is tested in combination with DIN-Rails according to EN 60715 with a
height of 15mm and a thickness of 1.3mm and standard orientation.
LABS compatibility As a rule, only non-silicon precipitating materials are used. The unit conforms to the
LABS criteria and is suitable for use in paint shops.
Corrosive gases Tested according to ISA-71.04-1985, Severity Level G3 for a service life of minimum
10years in these environments.
Audible noise Some audible noise may be emitted from the power supply during no load, overload or
short circuit.
