· Standardize electric vehicle charging and remember the safe usage guidelines!

The seemingly inconspicuous electric vehicle has repeatedly triggered deadly fires, causing serious damage to life and property. 80% of electric vehicle fires are caused by illegal charging.1. Improper charging operationCharging is prohibited in public spaces such as stairwells, fire exits, and evacuation safety exits. Charging is also prohibited indoors and near flammable materials. During the charging process, the charger generates a large amount of heat. The battery and its charging device should be placed in an open and well ventilated area for charging. Do not cover the charger or battery with combustible materials, as heat accumulation can easily cause a fire.2. Privately connecting and randomly pulling wires for chargingIt is prohibited to connect or pull wires privately. If the diameter of the charging line is too small and no short circuit or overload protection device is adopted, it is easy to cause a short circuit or heating of the line, which can lead to fire accidents.3....

· Three major drawbacks of push-pull switching power supplies

In the vast and complex field of power supply, push-pull switching power supplies were once like a shining star, widely used in many different fields. However, do you really understand clearly? In fact, it does have three major shortcomings that cannot be underestimated!push-pull switching power supplyFirstly, the circuit structure of push-pull switching power supplies has a high level of complexity. Specifically, it requires the use of more electronic components and complex wiring to achieve its functionality, which means that during the design phase, engineers need to spend a lot of time and effort planning and optimizing circuit layouts to ensure the stability and reliability of the power supply. In the manufacturing process, higher levels of craftsmanship and quality control are also needed to avoid performance degradation or failures caused by manufacturing defects. Moreover, once a push-pull switching power supply malfunctions, due to the complexity of its circuit, repairing and...

· How to avoid the danger of short circuits in chargers?

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...

· What are the effects of not unplugging the charger for a long time?

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...

· What is the difference between medical power supplies and regular power supplies?

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...
