What are the safety precautions power adapter?
Latest company news about What are the safety precautions power adapter?

Power adapter is a small portable electronic devices and power supply power transformation equipment, electronic appliances are generally controlled by the shell, inductor, capacitor, transformer, composed of components such as IC, PCB, it works by converting ac input dc output;According to the connection mode can be divided into wall type and desktop type two kinds.A wide range of products for security cameras, routers, article lamp, set-top boxes, massager equipment.

Will have a label on the power adapter, marking the power, input and output voltage and power flow indicator, special attention should be paid to the input voltage range, this is known as "travel power adapter, if to the mains voltage is 110 v, this feature is very useful, some of the gray notebook computers are sold only in country of origin, not compatible with the design of the voltage, even only a single input voltage 110 v, 220 v mains voltage on in our country will be destroyed.

 

Matters needing attention

A, the nominal voltage and electric current of the power adapter is what mean?

First of all, the general power supply of the nominal voltage, refers to the open circuit output voltage, which is outside don't pick up any load, when no current output voltage, can also be understood as, the voltage is the upper limit of output voltage.For use inside the power supply under the condition of the active voltage components, even if the mains voltage fluctuation, the output is also a constant value, as general small transformer on market, such as the distribution of power supply such as tablets, if there are fluctuations mains, the output of the power supply will not subsequently and volatility.

 

Second, the power of the nominal voltage is the same, the output current is different, can use in the same laptop?The power supply voltage is the same, and the output current is different, can use in the same laptop.The basic principle is a large nominal current of the power can be instead of the small nominal current power supply.Probably someone will think so, think big nominal current of the power supply will burn out his notebook, because the current is larger.Actually how much current is under the condition of the same voltage depends on the load.Third, the same machine, the power of the others had, I always very hot, why?Don't doubt your power supply has a problem, first take a look at your notebook is doing, as it says two USB hard drive, hard drive crazy to read and write, read the disk drive full speed CPU run at full speed, to recharge the battery at the same time, playing the music loud, biggest screen brightness, etc., make good use of power management, according to the reasonable task from adjusting the working state of the notebook is very important.

 

So an appropriate power adapter is the requirement of a safety certificate, according to the approval of the power adapter can protect personal safety.Prevent electric shock, fire and other dangers.You also know what power adapter considerations, to welcome you all to discuss. if any questions email to shawn@yhypower.com.
