14. Derating
The PS-60 power supply runs in nominal operation without any limitations. For operation
outside the nominal range, the following points should be observed depending on the type of
use.
14.1 Ambient Temperature
When operating the power supply at an ambient temperature of > 60°C, a power derating of
2.5%/K should be observed. Up to an ambient temperature of 40°C, the power supply can
take power from the static boost for a sustained period. In the 40°C to 60°C temperature
range, the power supply can output more than the nominal power for a sustained period.

14.2 Installation Height
The power supply can be operated at an installation height of up to 2000 m without any
limitations. Different data applies for installation locations above 2000 m due to the differing
air pressure and the reduced convection cooling associated with this (see technical data
section). The data provided is based on the results of pressure chamber testing performed
by an accredited test laboratory.
