This section describes the different mounting orientations and the effect that mounting orientation has on power supply performance 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 are referenced in Figure 2 1 e Curve Al Recommended output current e Curve A2 Maximum allowed output current which results in approximately half the lifetime expectancy for the power supply when following curve A1 iyi Note National Instruments recommends that the power supply be oriented such that the output terminals are located on top and the input terminals located on bottom Figure 2 1 refers to this as the Standard Orientation National Instruments Corporation 2 1 NI PS 15 Power Supply User Manual Chapter 2 Installation and Configuration Output Current Mounting Orientation A Standard Orientation 3 L mbient Temperature 04 pe 10 20 30 40 50 60 C Output Current 12A LIC Mounting 9 DX A2 Orientation B 6 Al Upside Down g 0 _ Temperature 10 20 30 40 50 60 C Output Current Mounting Orientation C s s Table top P
