What parameters does the power adaptors have?

The power adaptors, also known as external power adaptors, is a voltage conversion device for small portable electronic devices and electronic devices. It is widely used in small electronic products such as mobile phones, LCD monitors and notebooks. It consists of housing, transformer, inductance, capacitor, control IC, PCB and other components. Its working principle is converted from AC input to DC output; Depending on the connection method, it can be divided into wall type and desktop type.

What parameters does the power adaptors have?

1. Model, for example, model XVE-120100.It displays several information including manufacturer and main parameters. The beginning of XVE is ## company code, 120100 means that the adapter is 12V1A, and 050200 is 5V2A;

2.INPUT(input), commonly used in China, is AC100-240V~50-60Hz, which means that this adapter can work normally under an AC voltage of 100V-240V;

3.OUTPUT(output), DC 12 V e1 A, which is a DC current with a rated voltage of 12 V and a maximum current of 1 A. Two numbers can quickly calculate the wattage of the adapter, for example, the adapter, voltage 12 V, current 1 A12W (power), indicating that this power adaptors is a 12-W adapter.

What is the difference between a power adaptors and a charger?

The charger refers to a device that converts alternating current into low voltage direct current. The charger is a dedicated DC power adaptors for rechargeable batteries. It includes current limitation, voltage limitation and other control circuits that match the charging characteristics. Direct charging, without intermediate equipment and devices.

The power adaptors is a market standard inverter that is transformed, rectified and regulated. The output is DC, which can be understood as a low voltage regulated power adaptors when it meets power. The power adaptors is externally connected with a line to the host, which can reduce the size and weight of the host, and few appliances and electrical appliances have the built-in power adaptors in the host.

What are the advantages of a power adapter?

1. Small size and light weight.

The switching power adapter does not use a bulky power frequency transformer, because the power dissipation on the switching MOS tube is greatly reduced, and a large heat sink is omitted. Due to these two reasons, the switching power adapter is small in size and light in weight.

2. Low power consumption and high efficiency.

In the switching power adapter circuit, under the excitation of the excitation signal, the switching MOS tube works alternately in the on-off and off-on switching states, the conversion speed is very fast, and the frequency is generally above 50kHz, which makes the switching MOS tube The power consumption is very small, and the efficiency of the power adaptors can be greatly improved, and its efficiency can reach 90%.
