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.

What is the operating temperature of a power supply?

The operating temperature specified for a power supply refers to the temperature of the environment around it, rather than the external ambient temperature of the equipment. Typically, the operating temperature range for power supplies is between 0°C and 40°C, with some products able to reach standards of 0°C to 50°C.

Why should you choose a wide temperature power supply?

To address such extreme environments, users are advised to opt for wide temperature (Wide Temperature) power supplies. These devices are designed to provide stable power even under high or low-temperature conditions, ensuring the reliable operation of connected equipment.

Does a wide temperature power supply overheat?

Although wide temperature power supplies utilize internal components with superior heat resistance, these materials still have thermal and efficiency limits. When the ambient temperature exceeds 40–50°C (depending on the product design), internal components may overheat, leading to performance degradation and reduced output power.

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.

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.
