· To purchase a USB plug board, please recognize the "3C" logo

Mobile phones, computers, Bluetooth earphones, mini speakers... In modern life, various electronic devices cannot do without chargers. When the plug in ports at home are not enough, people buy USB plug ins one after another, which can be easily charged by plugging in a data cable, making it very convenient. On March 21st, State Grid Shanxi Electric Power Company reminded that when purchasing USB patch cords, please follow the "3C" logo, choose products from reputable manufacturers, and pay attention to safety precautions when using them to avoid electric leakage. Compared to regular power strips, power strips with USB interfaces can not only direct 220V AC power to convenient locations, but also convert AC power into DC output. A qualified USB plug board with components such as capacitors, transformers, and fast charging protocol chips, capable of stable voltage output.Electric power personnel remind that the internal capacity of power strips with USB interfaces is limited, so the...

· A fully plugged charger is not "convenient" but "dangerous"!

One of the things that many people love to do is to plug different types of charging cables into the power strip, such as phones, headphones, tablets, etc. They call this behavior "convenient", but it's like a "time bomb". A charger is a device that converts high voltage electricity into low voltage direct current. If left on a power strip for a long time without pulling it out, it will continue to heat up, accelerate the aging of the equipment, and easily cause short circuits or high voltage breakdown, leading to fire hazards.The charger cannot be charged in an environment that is too cold or too hot. So, when charging, be careful to avoid household appliances such as refrigerators or ovens, or places that can be directly exposed to the sun. If the environment where you live is often in a high temperature state, it is recommended to equip some high-performance and high-temperature resistant switch transformer charging heads.Do not charge near the bedside and bedsheet. Many people...

· Do you know what types of power supplies there are?

In modern society, power is ubiquitous and an indispensable part of our lives. From the batteries that provide energy for our electronic devices to the powerful generators that drive large industrial equipment, imagine that without power, our world would be plunged into darkness. There are no lights, televisions, computers, phones, cars, or airplanes.Kinri's Switching Power SupplyHowever, the world of power is not easy to understand. It is full of various complex technologies and mysterious powers. Different types of power supplies, such as DC power supplies, AC power supplies, switching power supplies, etc., have their own unique characteristics and application scenarios. Today, I will mainly take you to see what types of power supplies are available.DC power supply: Output DC power, such as batteries, batteries, DC stabilized power supplies, etc.AC power supply: Output AC power, such as mains power, generators, etc.Switching power supply: an efficient power conversion device widely...

· What is the main difference between a switching power supply and a regular power supply?

Working principleOrdinary power sources (such as linear power sources) typically use traditional transformers and rectifier filtering circuits to convert and regulate voltage. The current flows continuously through the entire circuit, resulting in high losses and relatively low efficiency.linear power supplySwitching power supplies use switch converters and pulse width modulation technology. It converts direct current into high-frequency alternating current by quickly switching switching switching tubes, and then performs voltage transformation and rectification filtering through transformers to provide stable direct current output. This method can achieve efficient energy conversion and improve the efficiency of the power supply.Switching power supplyPerformance characteristicsEfficiency: The efficiency of a switching power supply is usually higher than that of a regular power supply because it operates in a switching state, reducing energy loss.Volume and weight: The high-frequency...

· What is a shell type switching power supply and what scenarios can it be applied to?

There are two types of power supplies, organic shell type and open frame type, and their application scenarios are also different. Now let's take a look at what a shell type power supply is and its application scenarios.Open Frame Type power supplyShell type switch power supplyDefinitionShell type switching power supply refers to a switching power supply that is wrapped with a metal casing on the outside of the power supply. The advantages of this power supply are its lightweight and complete safety regulations.The application scenarios of shell type switching power supplies are quite extensive, and there are several common ones as follows:Consumer electronicsSuch as mobile phones, tablets, laptops, televisions, etc. These devices typically require small and efficient power sources to provide stable electricity.Household appliancesSuch as refrigerators, washing machines, air conditioners and other large household appliances, as well as electric fans, hair dryers, soybean milk machines...
