Outdoor power supply storage temperature

Do power supplies need to be housed outside?

Power supplies need to be housed outdoors, where the extreme heat of the summer and the extreme cold of the winter will both be present. Power supplies heat themselves up at different rates and intensities, and environmental influences will impact how quickly a power supply is exposed to high temperatures.

How does temperature affect a power supply?

Chemical processes accelerate, and mechanical connections can even loosen. The longer a component is operated at high heat, the more elevated temperatures can reduce its lifespan. Reduce the power supply load: Power supplies typically have specified loads according to an ambient temperature range.

Should a power supply be sealed?

The device’s operating environment will also determine whether the power supply will need to be sealed, such as preventing water and dust ingress, or if it can be vented to improve airflow. Some applications must withstand a wide range of operating temperatures, particularly outdoors. Take traffic control, for instance.

How thermal environment affects power supply success?

How Thermal Environment Impacts Power Supply Success. Operational temperature range can make or break a design. Choose wisely. Selecting the right AC/DC power supply for a given application starts with the environment.

What happens if air and power supply are the same temperature?

If the fluid (air) and the power supply (the hot object) are the exact same temperature, no heat will be transferred. Without allowing heat to move away from the outside of the power supply, its temperature will begin to rise as well, further impeding the effects of conduction.

How does ambient temperature affect power supplies?

Ambient temperature impacts the behavior, performance, and reliability of power supplies, making the environment a critical factor in their selection.
