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.

The power adapter is a small portable electronic device and the power supply conversion device of the electronic appliance is commonly used in small electronic products such as mobile phones, liquid crystal displays and notebook computers. Generally, it is composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into an AC output type and a DC output type; according to the connection mode, it can be divided into a wall type and a desktop type.

Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps , communications equipment, audio-visual products, security, computer chassis, digital products and instruments, and so on, and in these areas have a role to play.

So what are the functions of the power adapter? The power adapter space is generally built-in, the general adapter is not small, the small size of the machine is external, in order to save space, the second is also convenient to replace, adapter The mains electricity, the voltage is relatively high, it is dangerous to put inside the machine. Most notebook power adapters are suitable for 100 to 240V AC (50/60Hz). Basically, most laptops have external power supplies and are connected to the main unit with a power cord. This reduces the size and weight of the mainframe. Only a very small number of models have built-in power in the mainframe.

There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity. Pay special attention to the range of input voltage. This is the so-called “travel power adapter”. If the mains voltage is only 110V. This feature is very useful. In short, the role of the power adapter is to convert the high voltage into a stable low voltage that can work, so that the active device can work normally.
