Mounting Orientations
Mounting orientations other than vertical require a reduction in continuous output current or a limitation in the
max. allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply.
Therefore, two different derating curves for continuous operation can be found below:
Curve A1
Recommended output current.
Curve A2
Max allowed output current (results approx. in half the lifetime expectancy of A1).
