Derating

16.1

Temperature-dependent derating

With an ambient temperature of up to +60°C, the device

supplies the continuous output current of I

N. In the case of

ambient temperatures above +60°C, the output current must

be reduced by 2.5 % per Kelvin increase in temperature.

The device does not switch off at ambient temperatures of

+70°C or thermal overload. The output capacity is reduced

as far as necessary to provide device protection. After it has

cooled down, the output capacity is increased again.

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).

16.3

Position-dependent derating

The power supply can be installed onto all 35 mm DIN rails

according to EN 60715. The normal mounting position of the

power supply is horizontal.

When installing in a different mounting position, derating

should be adhered to.

The characteristic curve can be used to determine the

maximal output power to be drawn for each ambient

temperature for different mounting positions.
