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.

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.

temperature

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.
