25.13. 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 A1 Recommended
output
current.
Curve A2
Max allowed output current (results in approximately half the lifetime expectancy of A1).
