According to the connection method, it can be divided into wall type and desktop type. Widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.
How do we choose the right adapter?
What are the relevant parameters of the adapter?
What is the function of the power adapter?
When designing the right AC adapter for your device, manufacturers can also support a wide voltage range by choosing an external power supply. Finally, external power adapters are easier to replace. Users don't have to throw away their equipment if voltage spikes, or in the case of a power failure or electrical fire, destroy their external power supply unit.
Check the electrical ratings and choose the right AC adapter for your device
Before trying to find a matching AC adapter for your device, check that an OEM (original equipment manufacturer) adapter is available. Equipment manufacturers sometimes provide replacement chargers/adapters for their products. If this OEM accessory is available, it becomes easier to determine how to select the proper power adapter for the device. Find the specific adapter for your device by searching using the model number printed on the adapter that came with the device.
The AC symbol is a wave, while the DC symbol is a solid dash with three short dashes below it. The DC voltage is the output voltage of the adapter, which is usually much lower than the input AC voltage.
The voltage is measured in volts (V), and the current rating ends in amps or amperes (A). Power adapters have an AC input and a DC output. Depending on the region, the AC input can be either 110/120 V or 220/240 V. To make it easier for users to choose an AC adapter, manufacturers often provide adapters that support both voltages. Dual voltage adapters are listed for input AC voltages ranging from 110 - 220VAC or 100 - 240VAC. these are most useful for travelers researching how to select the correct power adapter for other parts of the world. The direct current voltage (VDC) of a power supply accessory is just as important as its alternating current voltage (VAC). When reading the adapter label, the VDC will be located below the DC symbol.
The AC symbol is a wave, while the DC symbol is a solid dash with three short dashes below it. The DC voltage is the output voltage of the adapter and is usually much lower than the input AC voltage.
Generally speaking, the role of the power adapter is a transformer and a rectifier. Household AC power is 220v, and our computer ground is DC 12v (as if it were), so we can be sure that the power adapter is a transformer and rectifier. The adapter is a transformer, so we should all know that AC 220v is transformed through the transformer and DC through the rectifier. There is consumption here, and this consumption will be converted into heat, so it is normal for the power adapter to heat up.
