1)
Parameter Ambient temp = 40°C (104°)
Ambient temp = 0 ... 40°C (32°...104°F)
Over 40°C: - current reduction of 2% of rated output current per K
- remove front plate (better than class 3K3 as per EN50178)
2)
Parameter Ambient temp = 50°C (122°F)
Ambient temp = 0 ... 50°C (32°...122°F)
Current derated to 0.8 rated ouput current
Over 40°C (104°): removal of the top cover (better than class 3K3 as per EN50178)
3)
Greatest relative air humidity occurs with the temperature @ 40°C (104°F) or if the temperature of the device is brought
suddenly from -25 ...+30°C (-13°...+86°F).
4)
Greatest absolute air humidity if the device is brought suddenly from 70...15°C (158°...59°F).
