What is a wide temperature power supply?
Wide temperature power supplies usually operate within a range of -40 to -20°C up to 70–80°C, exceeding the range of conventional power supplies and meeting the needs of most applications. Although wide temperature power supplies utilize internal components with superior heat resistance, these materials still have thermal and efficiency limits.
What is the operating temperature range for power supplies?
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. In other words, the temperature inside the equipment must be maintained within this range to ensure stable operation.
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 happens if a power supply reaches a high temperature?
When the ambient temperature exceeds this range—such as during scorching summers or freezing winters—the power supply may fail to operate normally. To address such extreme environments, users are advised to opt for wide temperature (Wide Temperature) power supplies.
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.
