· The Function and Working Principle of Power Protector

A power protector is a device used to protect power equipment in the power system. Its main function is to monitor and control the power supply to ensure the safe operation of the power system. In modern society, electricity is the foundation for the normal operation of various equipment and systems, and there are various faults and abnormal situations in the power system. The power protector monitors the power status in real-time, detects faults and abnormalities, and takes corresponding protective measures to ensure stable power supply of the power system. This article will introduce the definition, functional functions, and detailed explanation of the principle and working mode of power protectors.Power surge protector1. What is a power protector？A power protector is a device specifically designed to protect power equipment in a power system. It mainly monitors the voltage, current, frequency and other parameters of the power supply in real-time, and monitors and controls the power...

· What are the differences between the applications of switching power supplies and linear power supplies?

In the electronic world, switching power supplies and linear power supplies are two very important roles. Although both are power supplies, they have many significant differences.Let's talk about efficiency first. Switching power supplies are like highly efficient little experts, with an efficiency of over 80%, while linear power supplies are slightly inferior in this regard, usually only around 50%. This can directly affect the efficiency of energy utilization!120W Din Rail Switching Power SupplyIn terms of volume and weight, switch mode power supplies have the advantage of high-frequency operation, with small transformers and other components, making them lightweight and portable overall; Linear power sources, on the other hand, appear somewhat cumbersome due to their larger transformers.In terms of heat dissipation, switch mode power supplies generate less heat and have relatively low requirements for heat dissipation; Linear power supplies, on the other hand, require more careful...

· Is the wireless charging radiation of mobile phones too high to buy? The measured data will tell you the answer

The addition of wireless charging function to high-end mobile phones has gradually made wireless charging technology known to the public. This is not a novel technology, but many people are still not familiar with it. One of the issues is whether wireless charging has radiation. Some netizens even said, "The radiation of wireless chargers is even greater than that of mobile phone networks." So, how much radiation will seemingly high-tech wireless chargers bring to our daily use? Will it harm our health and safety? Now let's have a detailed discussion with everyone.Apple 8x Wireless ChargerThe principle of wireless charging is actually very simple. The famous principle of electromagnetic induction serves as its theoretical basis. Simply put, when current flows through a coil, a magnetic field is generated, and coils close to the magnetic field generate induced current, thereby achieving wireless transmission of current. The whole process is actually very simple, just like a transformer...

· Can the Type-C power port of a laptop be charged with a high-power mobile fast charger?

In the era of rapid development of modern technology, the charging methods of electronic devices are also constantly upgrading. Type-C power port, as a new interface standard, is gradually becoming popular and applied in devices such as laptops and mobile phones. At the same time, high-power fast charging chargers for mobile phones are also selling well in the market. So, can the Type-C power port of a laptop be charged using a high-power mobile fast charger? Let's explore the truth.Type-C power port mobile fast chargerFirstly, we need to understand the characteristics of the Type-C power port and high-power fast charging chargers for mobile phones. Type-C power port is a new interface standard that has the advantages of being compact, portable, easy to plug and unplug, and correctly inserted in both directions. The high-power fast charging charger for mobile phones has the characteristics of high output voltage and high output power. This type of charger can quickly charge mobil...

· Does the length of the Type-C charger data cable affect the speed of phone charging?

The length of the data cable affects the resistance of the metal wires inside. In the past, when there was no fast charging, the length of the data cable determined the speed of phone charging. So, does the length of the Type-C charger data cable affect the speed of phone charging now? Someone used three Type-C data cables with lengths of 51cm, 117cm, and 1.5m, and tested them under the same power of 45W.Type-C charger data cableThe experimental results show that the charging speed of the three types of data cables used by the user is similar, and there will be no difference in the power transmission of the device. Currently, the power of Type-C chargers is mostly above 45W, and the main factors affecting the charging speed of mobile phones are the power of the charger and the input voltage of the battery. The length of the data cable has little effect on the speed of phone charging. Therefore, we can choose the length of the data cable according to the situation. When using a mobile...
