Switching Frequencies
The power supply has two converters with two different switching frequencies included.
Switching frequency 1 70kHz to 130kHz PFC converter, input voltage and output power dependent
Switching frequency 2 80kHz to 140kHz Main converter, output power dependent

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 30W/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
LABS compatibility The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
Audible noise At load currents below 1A some audible noise will be emitted from the power supply
*) 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.
***) Higher levels allowed when using the 1606-XLC wall mounting bracket.
