Why should a power supply have a wide operating temperature range?

Depending on the application, a power supply with a wide operating temperature range may provide better reliability and a longer operating lifetime, prevent the need for a cooling fan or other special design consideration for thermal management, and reduce the overall cost of your system.

What temperature should a commercial power supply be rated?

Typical commercial power supplies are specified to support their full rated load over an ambient temperature range from zero or minus 25 degrees Celsius to around 50 degrees Celsius, and they may derate to 50% load at 70 degrees Celsius.

Are outdoor power strips weather resistant?

Outdoor power strips come in a variety of sizes, from small three-outlet models up to large 10-outlet beasts. Unlike indoor models, these rugged, weather-resistant power strips can endure extreme temperatures and even downpours. Understanding what weather conditions an outdoor power strip is rated to handle is key to purchasing the right one.

What is a good ambient temperature for a power supply?

Some applications may require ambient operating temperatures as low as -40 degrees Celsius and as high as +85 degrees Celsius, or an even wider range. A number of factors can influence the ambient temperature that a power supply is subjected to in a given application, including the following:

What does it mean if a power supply exceeds standard operating temperatures?

Exceeding standard operating temperatures means running your power supply when the ambient temperature falls outside the operating temperatures for which it is rated. Sometimes this happens — you can't predict every possible usage scenario, and you can’t always guarantee a stable environment.

What is a high-efficiency power supply?

This means that a power supply with a wide operating temperature range is likely to have a high-efficiency rating as well. Power supplied with lower efficiencies are more likely to require aggressive cooling methods to maintain their reliability at higher ambient operating temperatures.
