Operational temperature
*) -25°C to +70°C (-13°F to 158°F) reduce output power according Fig. 14-1
Storage temperature -40 to +85°C (-40°F to 185°F) for storage and transportation
Output de-rating 2W/°C 60-70°C (140°F to 158°F)
Humidity **) 5 to 95% r.H. IEC 60068-2-30
Vibration sinusoidal 2-17.8Hz: ±1.6mm; 17.8-500Hz: 2g
2 hours / axis
IEC 60068-2-6
Shock 30g 6ms, 20g 11ms
3 bumps / direction, 18 bumps in total
IEC 60068-2-27
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. 14-2
IEC 62103, EN 50178, overvoltage category II
Altitude de-rating 5W/1000m or 5°C/1000m > 2000m (6500ft), see Fig. 14-2
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
*) Operational temperature is the same as the ambient temperature and is defined as the air temperature 2cm below the unit.
**) Do not energize while condensation is present
