MVAC400 Series
400W 3" x 5" High Density AC-DC Power Supply Converter
THERMAL CONSIDERATIONS
System thermal management is critical to the performance and reliability of the MVAC series power supplies. Performance derating curves are provided
which can be used as a guideline for what can be achieved in a system con?guration with controlled air?ow at various input voltage conditions.
The air ?ow curves are generated using an AMCA 210-99 and ASHRAE 51-1999 compliant wind tunnel with heated inlet air and a controlled CFM
providing a duct test section having a calculated average LFM. A correlation between the test setup and the actual system environment is paramount to
understanding what can be achieved in an actual system. In a power supply of this density, cooling air moving both through the unit as well as around the
unit strongly in?uences local temperatures. The wind tunnel test setup was constructed to produce a ?ow with a slight back pressure to induce both ?ow
conditions by providing a small gap between the power supply and duct walls of 0.5" (13mm). The optimal and characterized air?ow direction is from the
input connector to the output connector (see diagram below). The P-Q ?ow curve for this test setup is also shown below.

The natural convection data is obtained from a horizontally mounted power supply with un-obstructed ?ow at room temperature. At elevated temperature
the power supply data is taken while it is surrounded by a large vented enclosure to minimize forced cross ?ows inherent in the elevated temperature test
system.
