Now science and technology unceasing progress, people living standard will be improved.
The development of economy will follow.
Predictably, mobile phone, computer, TV and other electronic equipment is everywhere in our daily life, but you ever think of when we use the small electronic products, they also need to provide electricity to use.
This time the power adapter is their power sources.
But this time people rely on electronic products is more and more big, the life cannot leave a mobile phone, computer, TV and other electronic equipment, life everywhere need them.
Easy to phone your emergency contact with others, which is convenient for you to use mobile phone chat software and friends and family relationship, you can query information online, convenient life stress, and so on.
But when it comes to power adapter may be a lot of people don't know what is this, if the laptop charging online the rectangle parts or mobile charger is common, yes, that is the power adapter is a small power supply power transformation equipment, used in portable electronic devices or electronic appliances, more like our common console, walkman, notebook computers, mobile phones and so on all need our power adapter.
Its role is to put the home of 220 v high voltage into the electronic products can work around 5 v to 20 v low voltage stability, so they can work normally.
In the following interpretation of the popularization of about what is the power adapter?
Actually simple, the function of the power adapter is the effect of variable pressure, namely the high power AC voltage, through the rectifier power adapter, transformer, converted to low voltage DC power, such as input: 100 -
12 VDC 1 a which is 60 hz output: the high pressure - 100
Transformed into 240 v low voltage 12 v.
In general have a nameplate on the power adapter, the following marked power, output to input voltage and current goals, special to pay attention to the category of the output voltage, this is the so-called & other;
Visit the power adapter & throughout;
, if the mains voltage as long as the kingdom of 100 v, this feature is very effective, some import to remember this computer is only sold in the country of origin, there is no such plan, and as long as the single output voltage 100 v, 220 v mains voltage on in our country will be discarded.
The power adapter is common in mobile phones, LCD display and laptop computers and other small electronic products.
Generally consists of shell, power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output;
According to the connection mode can be divided into the plug wall and desktop type.
Widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps and lanterns, communications equipment, audio and video products, security, computer case, digital products and equipment, and other fields, and in these areas have the effect that cannot ignore.
By the way, the role of adapter is to convert alternating current into direct current electronic products.
Below bringing everyone know about the power adapter on the label need to be aware of: the first, the adapter models, models are XVE - for example of the adapter
050200, it tells us a few information, is its manufacturer, wattage, etc. , XVE beginning general is # # company code of 050200 is that this adapter 10 w.
Second, adapter INPUT (
, gm in China usually is 100 -
240 v ~ 50 -
60 hz, this suggests that the adapter can be 100 v -
240 v voltage under the normal work;
The third is the OUTPUT of the adapter (
, two Numbers can be very fast to calculate this adapter wattage, this adapter, for example, voltage 5 v * current 2 a 10 w = (
That this power is 10 w adapter.
Third, there is a plaque on the power adapter, marked on the power, input and output voltage and power flow indicators, such as paying special attention to the input voltage range.
For the power adapter is what things?
We also have a certain understanding.
Moso technology of small make up hope that the above knowledge can help to you!
