When we hear the word radiation, the first reaction of many of our friends is fear. It reminds us of nuclear radiation, the Fukushima nuclear leakage, the Chernobyl incident. So most people are talking about the climate change, think that radiation will harm people's health, is not good. But the truth is that radiation is always present in our lives. Not only do cell phones emit radiation, but other appliances in our lives also emit radiation. Today we are going to talk about the radiation of power adapters.
First of all, let's understand what radiation is. Radiation refers to the phenomenon that part of the electromagnetic energy emitted by the field source travels away from the field source and does not return to the field source. The energy diffuses outward in the form of electromagnetic waves or particles. All objects in nature. As long as the temperature above the absolute temperature of zero, are in the form of electromagnetic waves and particles constantly transfer heat outward, this transfer of energy is called radiation. The radiated energy radiates outward from the source in a straight line in all directions. The energy given off by an object through radiation is called radiant energy.
For the power adapter, it produces two kinds of radiation, one is the thermal radiation that can be felt. Because the power adapter will generate heat in operation, so the power adapter will be hot, which will produce thermal radiation. Any object at a temperature above absolute zero produces thermal radiation. The radiation generated by the power adapter is mostly heat radiation of the circuit. For example, people near the stove can feel the heat, and this radiation is harmless to the human body. The other is electromagnetic radiation. Any electrical appliance will produce electromagnetic radiation after being switched on. However, with the development of technology, many high-quality power adapters now adopt good radiation isolation measures inside. Regular quality through the safety standard of the power adapter to produce the so-called radiation is safe and small, completely has no effect on the human body.
YHY power adapter from design to production testing are in strict accordance with safety standards to produce, all raw materials have passed strict quality certification, to ensure the quality and safety of products, the use of multiple circuit safety design, effectively prevent over current, over voltage, overheating, short circuit phenomenon, always keep the output voltage stable, better protect access to digital equipment, safe and harmless, Products also passed the CB/CE/GS/BSMI/KC/PSE/CCC/SAA/UL/cTUVus/FCC and other international quality system certification, the use of safe. Continuous supply of high quality power products for the society.
