20.13. Mounting Orientations
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 maximum 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).
