Bulletin 1606 Switched Mode Power Supplies
Switching Frequencies The power supply has three converters with three different switching frequencies
included. Two are nearly constant. The other one is input voltage and load dependent.
Switching frequency 1 35kHz nearly constant
Switching frequency 2 105kHz nearly constant
Switching frequency 3 40kHz to 220kHz input voltage and load dependent
15. Environment
Operational temperature *) -25°C to +70°C (-13°F to 158°F) reduce output power according Fig. 15-1
Storage temperature -40 to +85°C (-40°F to 185°F) for storage and transportation
Output de-rating 6W/°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. 15-2
IEC 62103, EN 50178, overvoltage category II
Altitude de-rating 15W/1000m or 5°C/1000m > 2000m (6500ft), see Fig. 15-2
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 in the presence of condensation.
