These conditions require an industrial UPS specifically manufactured to withstand high temperatures – one that has been agency-certified (e., UL) to have a wide operating temperature range of at least -20°C to 55°C (-4°F to 131°F).
Why does my power supply not start at cold temperatures?
If electrical characteristics change drastically enough, the power supply may not start at cold temperatures. Increase the risk of electrolytic capacitor seal failure: Extreme cold can cause electrolytic capacitors to fail, a catastrophic failure for the component.
What happens if a power supply temperature drops too low?
Electronics generally like the cold, but if the temperature drops too low, it can still cause problems. Low temperatures are more likely to affect performance than a power supply's lifespan. Low power supply temperatures can:
How does the orientation of a power supply affect heat buildup?
The orientation of a power supply can also affect heat buildup. Since hot air rises, a vertically mounted power supply tends to transfer heat to other components, but a horizontal power supply allows the air to move more easily via cooling methods.
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.
Why is rated operating temperature important?
The rated operating temperature of a power supply is necessary for optimizing performance. Increase the risk of failures and malfunctions: Exceeding operating temperatures can also hurt the equipment's reliability.
How do environmental factors affect a power supply?
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. Designers have to factor in the additional heat of nearby equipment, self-heating from high loads, and radiant heat such as solar energy on an enclosure.
