RIENTATIONS
 
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).
