16 Derating
The QUINT POWER 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.
16.1 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.

temperature
16.2 Input voltage
16.3 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.
