Installation and Configuration
This chapter describes how to prepare and operate the NI PS-15 power
supply.
Mounting Orientation and Installation
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:
•
Curve A1
—Recommended output current.
•
Curve A2
—Maximum allowed output current (which results in
approximately half the lifetime expectancy for the power supply when
following curve A1).
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
.
