Temperature resistance introduction

The temperature resistance and fire resistance of power adapters are not only directly related to the reliability and service life of the power adapter, but also directly related to the degree of risk of fire, which is related to the safety of the user's life and property. Today we will give you an introduction to the power adapter's temperature resistance.

The heat source of the power adapter is mainly Schottky rectifier diode, high-frequency switching transformer, power MOS tubes, electrolytic capacitors for filtering, among which the temperature rise of power MOS tubes, high-frequency transformer and rectified Schottky diode is more prominent. In order to prevent the power adapter from being damaged due to overheating, the design of the power adapter not only requires the use of high-temperature characteristics of good electronic components, and at the same time requires printed PCB boards, heat sinks, high-frequency transformers, etc., reasonable design, advanced production technology, and the need to take overheating protection measures, which are necessary in order to ensure the safety of the conditions that must be met.

In order to suppress the temperature rise of the power adapter, in addition to the selection of small leakage current, short storage time of the power MOS tube, but also need to add a heat sink to the power MOS tube. It has been proved that after the MOS tube is equipped with a heat sink, the stability of the power adapter will be greatly improved, and the loss rate is significantly reduced. The role of the electronic switch overheating protection measures is in the power adapter is prone to heat components or power supply shell temperature exceeds the specified limit value before, cut off the power adapter AC input line, or forced to shut down the modulation pulse output, stop high-frequency oscillation.

Eahunt only do high standard power supply, product 100% aging test, life expectancy can reach 100,000 hours, to meet the 10,000 times plugging and unplugging without failure standard. Product certification is complete, with CCC CE UL CB PSE KC GS, FCC multiple international safety regulations.
