What is the purpose of an open frame power supplies?

open frame power supplies reflect compliance with specifications and do not include any enclosures to promote heat buildup. Many unique factors arising from the application can affect the thermal performance of the power supply, such as the space around the power supply, heat dissipation from adjacent components, mounting location and orientation, the load to be applied, and available system cooling.

The datasheet for an open power supply may list power ratings that reflect the expected results because it has been tested for forced air cooling, convection cooling, or both. However, once an open frame power supply is installed, you should test the entire end product system under any conditions that may push the internal temperature of the end product to its maximum. If the maximum temperature of individual critical components is reached or exceeded, additional cooling or reinstallation in a different location may be sufficient to reduce operating temperatures. If an open power supply is located in an inadequately cooled chassis, components that exceed their maximum temperature rating will be damaged. Damaged components may not immediately affect performance, but damage can lead to premature failure or a more rapid degradation of performance.

Thermal management is already part of the five performance dimensions of power conversion and is a standard that SL Power engineers strictly adhere to. The five performance dimensions are thermal management, reliability, EMI/EMC performance, power efficiency and power density, collectively known as TREPP.

How does the safety of use of an open power supply manifest itself?

If open power supply measurements are not considered during the design phase, spacing issues can lead to last minute failures once the application is built. Installing an open power supply inside an equipment enclosure requires careful observation of clearances and creepage distances on all sides. Creepage distance is the path between the electrical components and the boundary of the equipment enclosure, measured along any insulating surfaces present. Insulation creates conductive paths that can lead to short circuits, which can lead to fires, so observing the distance to avoid creepage is a safe practice.
