How much do you know about the performance characteristics of mobile phone chargers?

The quality of mobile phone chargers produced by Changzhou Shengdan Electric Appliance Co., Ltd. is very good. The company has long insisted on pioneering and innovation, paying full attention to the human factor and giving full play to the enthusiasm of its employees. On the other hand, enterprises pay attention to their own credibility, and regard credibility as the foundation of enterprise survival and the source of development. Let's follow the editor to learn more about the performance characteristics of mobile phone chargers! In our daily use of mobile phone chargers, we can test its performance. For example, in the later stage of charging, the battery will heat up a little. If the battery is obviously hot, it means that the charger does not detect that the battery is fully charged, which will cause overcharging to be bad for the life of the battery.  In fact, there is basically no overcharging in normal use, but there will be a problem of insufficient charging. This is usually seen in the battery discharge time. For users who are using the original new battery, you can compare the approximate reference time provided in the manual. If the reference value is very different from our daily use, then you can be sure that this mobile phone charger has However, other factors such as the quality of the battery and the environment in which the mobile phone is used cannot be ruled out. The above are some detailed introductions about the performance characteristics of mobile phone chargers. I hope they will help you after reading them.

What are the uses of the Santan switching power supply manufacturers tell you?

Switching power supply is also known as switching power supply and switching converter. It is a high-frequency electric energy conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of switching power supply is mostly AC power or DC power, but most of the output is equipment that requires DC power. For example, in your own computer, the switching power supply performs voltage and current conversion between the two. The Santan switching power supply uses more than half of the switching transistors to switch between the fully open mode and the fully closed mode. These two modes will have the characteristics of low dissipation, and the conversion between switching will have high dissipation, but The time is relatively short, so it saves energy and generates less waste heat. Usually the switching power supply itself does not consume power. Voltage stabilization is also achieved by adjusting the time when the transistor is turned on and short-circuited. Due to the high operating frequency of the switching power supply, a small size and light weight transformer can be used, so it is small in size and light in weight. If the efficiency of the power supply is high, and the volume and weight are the key considerations, the switching power supply is better. The only thing is that this is more complicated, and the internal transistors are also frequently switched. If the switching current can be processed, noise and electromagnetic interference may be generated and affect other devices. Switching power supply products are widely used in industrial automation control, scientific research equipment, LED lighting, industrial control equipment, communication equipment, electrical equipment, instrumentation, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual Products, LED strips, computer cases, digital products and instruments and other fields.
