Mounting orientations other than input terminals on the bottom and output on the top require a reduction in

continuous output power or a limitation in the maximal 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 in approximately half the lifetime expectancy of A1).
