Power Supply Operating Temperature

What is the meaning of Power Supply Operating Temperature?

Power Supply Operating Temperature refers to the range of ambient temperatures within which the power supply unit (PSU) can function reliably and safely.

This specification is important because extreme temperatures—either too hot or too cold—can reduce the efficiency, stability, or lifespan of the power supply, potentially causing malfunctions or interruptions in service. By defining an operating temperature range, manufacturers ensure that the PSU can consistently deliver the necessary power to the satellite receiver, even in harsh outdoor conditions such as intense heat, freezing cold, or direct sunlight. Staying within this range helps maintain reliable satellite internet performance and protects the equipment from thermal stress or damage.
