120W Battery Charger 1. Use a suitable voltage socket for charging:Short circuit burning of mobile phone chargers may also be due to the use of high-voltage sockets or excessive external current. If the external current is too high, it can sometimes cause output short circuits or input short circuits in power supply overcurrent maintenance. Therefore, when charging, a suitable voltage socket should be used for charging.2. Purchase original charger:The necessity of purchasing original chargers and using original model phone chargers. At the mobile phone store, the owner brought out a phone charger without brand, certification, and instructions. When asked about its safety performance, the shop owner simply said, "If you're afraid of accidents, you'll buy the original factory. There must be a reason for cheap goods."3. Choose 3C certified products:As is well known, "3C" is the unified symbol for national mandatory product certification applications. The certified power adapter...

When charging a mobile phone, many people have the habit of not unplugging their charger, and some even haven't unplugged their phone charger for the whole year.So what are the effects of the charger being plugged into the socket for a long time when the phone is not charging? Let's take everyone to reveal the secret.The impact of not unplugging the charger for a long time1. Shorten the lifespan of the chargerIf the charger is plugged into the socket for a long time, due to the composition of the electronic components of the charger, there will be a slight current passing through the socket, which can cause heating and aging of the components, and some may even experience short circuits, greatly shortening the lifespan of the charger.2. Power consumptionThe charger has been plugged into the socket all the time. Although the phone has not been charged, the internal circuit board of the charger is powered on, so the charger is in working mode and will consume electricity.3. There are sa...
In today's society, with the rapid development of power technology and the increasing demand for equipment in the medical industry. After all, medical devices are electronic devices that come into direct contact with the human body. Firstly, the performance and accuracy of electronic devices are highly required, and the safety of the power supply equipment used in electronic devices must comply with national regulations. In the medical industry, there are many electronic devices, such as ultrasound X-rays, fetal monitors, and life monitors, that come into direct contact with the human body. When using these devices, it is necessary to avoid contact and radiation between the device and the human body. Therefore, there are strict requirements for the design and use of medical power supplies.Medical power supply is a power supply device that provides power security for medical equipment and institutions. Due to the high requirements of medical equipment for power quality, power supply re...
LED driver power supply is a type of power supply, which is just a specific type of power supply. This type of power supply drives LED lighting with voltage or current, and is one of the reliable power supply devices. How to judge the quality of LED driver power supply? In response to this issue, this article will provide a detailed introduction for everyone.High power LED driver power supplyHow to judge the quality of LED driver power supply?1. Driver chip: ICThe center of the LED driver power supply is the IC, and the quality of the IC directly affects the entire power supply. The driving ICs of large factories are all acquired by Jingyuan in search of large packaging factories to package; The driving IC skills of small factories are to directly copy the driving planning plan of large factories and find small packaging factories to package, which cannot guarantee the consistency and stability of the entire batch of ICs, and then cause the driving power supply to mysteriously fail af...
A switching power supply is a type of power supply that utilizes modern power electronics technology to control the time ratio of switching on and off, and maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. With the development and innovation of power electronics technology, switch mode power supply technology is also constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, lightweight, and high efficiency, and are an indispensable power supply method for the rapid development of the electronic information industry today. So what are the PCB design specifications for switching power supplies?PCB design specifications for switching power supplies:1. Establish component parameters from schematic diagram to PCB design process ->Input schematic network table ->Design parameter settings ->Manual layout ->Manual...
