Main products: power adapter, medical power, LED power, charger and so on.

The Unicom power adapter has a wide range of applications, fine workmanship, over-voltage, over-current standard design, safety and stability, real materials, quality and quantity, so that you can use more confidence.

It is a small rectifier transformer. For example, notebook power supplies, mobile phone chargers, etc., are all power adapters. The AC mains rectifier with a voltage of 220v is stepped down to a voltage level of 20V, 19V, 4.5V, etc. available for notebooks and mobile phones.

The power adapter is used to provide a power source that matches your appliance. Simply put, your appliance may not match the parameters of the mains or other power supply, and the power adapter is used for conversion.

The power adapter, which is a small and easy-to-carry electronic device in life, provides the same parameters for products that need to be charged, that is, the power supply device can be converted. The power adapter is generally composed of a casing, a power transformer, and a rectifier circuit. Moreover, the power adapter also has two output modes, generally the mode of the AC output and the DC output.

Widely used in telephone sub-machines, game consoles, language repeaters, walkmans, notebook computers, cellular phones and other equipment.

There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity, etc., especially pay attention to the range of input voltage. This is the so-called "travel power adapter", if the country has a voltage of only 100V This feature is very useful, some parallel laptops are only sold in the country of origin, without this design, even a single input voltage of 100V, will be burned when plugged in China's 220V mains voltage.

The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays and notebook computers. Its role is to convert the 220 volt high voltage in the home into a stable low voltage of 5 volts to 20 volts that these electronic products can work, so that they can work normally.
