23.12 Mounting Orientations
Mounting orientations other than all terminals on the bottom 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 A1Recommended output current.
Curve A2Max allowed output current (results in approximately half the lifetime expectancy of A1).
