How to select the right wall mount power adapters？

There is a wide variety of electrical devices, so it is not possible to use adapters for charging. Before choosing the power adapter to charge, it is necessary to determine the adaption conditions of the power adapter and electrical equipment.

As the heart of electronic equipment, the power adapter plays a vital role in the safe and reliable operation of electronic equipment. Which should pay attention to when choosing the power adapter?

First, whether the interface of the adapter is fully matched with the device.

Second, the output voltage must be the same as the rated input voltage of the load , or in the voltage range that the load can withstand, otherwise, the load may be burned.

Third, the output current of the power adapter should be equal to or greater than the load (mobile device) current to provide sufficient power.

The following is to analyze the above three conditions of adaptation.

First, the mismatched interface in the absence of professional knowledge, do not insert, otherwise it will be dangerous.

Second, for why the need for the same voltage, in principle is such a lack of voltage, the lack of to drive the load, the battery can not be charged normally, said the popular point is that demand exceeds supply.

Third, for why the need for such a current configuration, which involves the principle of the circuit, we all know that the power supply is internal resistance, the greater the loss of the greater the internal resistance. Therefore, the power adapter manufacturer in the production of this adapter will be based on the size of the internal resistance, determine the no-load output voltage in a certain range, and the voltage critical value corresponding to the current critical value is I see the nominal value of the current, the greater the nominal value of the current adapter load capacity is better. So choosing a slightly higher current adapter will not hurt the battery, but will make charging faster.

And we have wall mount power adapters for a variety of powers, as well as wall mount power adapters for different electronic devices. There is a wide variety for you to choose from.

In addition, it is necessary to consider the working environment temperature of the power supply, and whether there is additional auxiliary cooling equipment. The output of the power supply needs to be reduced in the excessively high ring temperature. Reference should be made to the reduction curve of ring temperature on output power.

And select various functions according to the application requirements:

Protection function: over voltage protection , over temperature protection , over load protection , etc.

Application functions: signal function (power supply normal, power supply failure), remote control function, telemetry function, parallel function, etc.

Special function: constant power supply.
