What temperature should a PSU run at?
Most PSU's are rated for full output at 25 C. A few more are rated for full output at 40 C. Most of the really good ones are rated at 50 C. 50 C is a pretty difficult standard to meet. Plus, better efficiency results in less wasted power and a cooler running power supply. It's running at 32C right now. The power supply is an ultra 500 watt.
How does temperature change between air and power supply?
As the air stays in proximity to the hot power supply surface, its temperature will rise. Eventually, the temperature will become equal to the temperature of the power supply surface. There is once again a dependence on a temperature differential between the two media.
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.
What temperature should a power converter be used in?
Most people are not interacting with electrical office equipment or hospital equipment in environments outside this range. These types of power converters can usually operate safely and reliably in environments between 40°C and 60°C with appropriate derating considerations.
What temperature should an AC/DC power adaptor be rated for?
The typical AC/DC power adaptor, enclosed in a plastic case, can be expected to offer its full nameplate-rated output power in ambient temperatures between 0°C and 40°C (32°F and 104°F). This range is ideal for devices used indoors—in an office, home, or similar setting—where people work or live.
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.
