13. Environment
Operational temperature *) -25°C to +70°C (-13°F to 158°F) see Fig. 13-1
Storage temperature -40 to +85°C (-40°F to 185°F) for storage and transportation
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 6000m (0 to 20 000ft) Reduce output power or ambient temperature
above 2000m sea level.
Altitude de-rating 5.8W/1000m or 5°C/1000m above 2000m (6500ft), see Fig. 13-2
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

14. Protection Features
Output protection Electronically protected against overload, no-load and short-circuits *)
Output over-voltage protection typ. 31Vdc
max. 32Vdc in case of an internal power supply defect, a redundant
circuit limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Reverse input polarity protection Included unit does not start when input voltage is reversed
Output over-current protection electronically limited *) see Fig. 5-1
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm e.g. screws, small parts
Over-temperature protection yes output shut-down with automatic restart
Input transient protection MOV Metal Oxide Varistor
Internal input fuse T10A H.B.C. not user replaceable
*) In case of a protection event, audible noise may occur.
