Adapter AC DC 12v 3a 36w

Step1:Confirm the output current and voltage of the power adapter

Step2:Confirm AC plug specifications,you can choose the US/UK/EU/AU/CN/SANS/India/Korea plug or other plugs.

Step3:Confirm DC head specifications,you can choose the DC connector 5.5*2.5mm, 5.5*2.1mm, 2.0*0.6mm, 2.5*0.7mm, 3.0*1.1mm, 3.5*1.35mm, 4.0*1.7mm, 4.5*2.7mm, 4.8* 1.7mm, 6.3*3.0mm, 7.4*5.0mm, 7.9*5.5mm, Cigarette butt DC head, USB, TYPE-C or other connector.

Step4:Confirm the cord length of the power adapter,the length of DC cable according to your requirements, you can choose 1m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m, 2.8m, 3m, 3.5m...

Step5:production process: SMT →PCB board plug-in → QC testing of the board → Wave soldering → Reflow soldering → Initial testing → Assembly → Full load aging testing → Full function testing → Packaging → QA inspection → Finished product storage.
         

Step6:Packing and delivery

First we need to understand what is an adapter?

An adapter is a design pattern used to convert incompatible interfaces into compatible interfaces so that two different systems or components can communicate and work together. The adapter pattern can hide incompatible interfaces and allow us to interact with other components or systems without changing existing code. Using the adapter pattern, we can add new features or integrate new components without changing the original code, which improves the flexibility and reusability of the system.

Secondly we focus on the 12V3A wall-mounted adapter?

It is a high-power wall-mounted power supply that converts household AC power into 12V DC power, which is very suitable for powering a variety of small devices, including LEDs, monitoring, routers, audio, cameras, speakers, TV boxes, scanners, digital photo frames, etc. In addition, if you need different output voltages and currents, we are happy to customize solutions to meet your unique needs. Whether it is 5V4A, 9V3A, or 15V2A, we can customize satisfactory products for you. We are committed to providing the best quality customized solutions to help you power your devices safely and efficiently.

Finally let's talk about the main differences between 12V3A wall adapters and desktop adapters:
1. Different appearance: 12V3A wall adapters are usually small in size and can be directly plugged into the socket for use, while desktop adapters are larger in size and need to be placed on the desktop or in the corner.

2. Functional differences: 12V3A wall adapters usually have only one power output interface, which is suitable for powering some household appliances or smart devices; while desktop adapters usually have multiple power output interfaces, which can charge or charge multiple devices at the same time.

3. Different installation methods: 12V3A wall adapters can be directly plugged into the wall socket for use, which is more convenient; while desktop adapters need to be placed on the desktop and take up a certain amount of space.

4. Different scope of application: 12V3A wall-mounted adapters are small in size and easy to use. They are usually used to power small appliances or smart devices in homes or offices; while desktop adapters are suitable for some home entertainment systems and industrial control systems and other devices that require high power output!

Q:Are you a trader or a factory?

Q:What production equipment does your factory have?

A:1. Equipment for processing circuit boards, including drilling machines, machines for removing copper foil, and chip placement machines.

2. Soldering equipment, such as wave soldering machines and manual soldering equipment, to ensure that all connections are firm and safe.

3. Winding machines are used to manufacture high-quality transformers and inductors to keep your electronic devices running smoothly.

4. Packaging machines, such as automatic packaging machines and heat shrink packaging machines, are essential to protect and display your finished products.

5. Finally, test equipment, including insulation testers and high-voltage testers, is essential to ensure that your products are safe, reliable, and ready for market. With these tools, you can ensure that your electronic products are of the highest quality and will perform as expected.

6. Computer-operated equipment, such as automated production lines and intelligent production control systems, improve the efficiency and productivity of the production process.

7. Noise test equipment is used to ensure that the adapter operates at an acceptable noise level and produces minimal interference.

8. Temperature test equipment is used to ensure that the adapter operates at a stable and safe temperature, providing reliability to the user.

9. Optical test equipment tests the optical performance of the adapter to ensure that it meets high quality standards, making it a reliable and trustworthy product.

Q:Do you only produce certified products?

A:No, although we have global product certification, we also produce non-certified products to meet the needs of global customers.

If your product does not meet our requirements, can you customize it for us? What aspects can be customized?

Of course, we can customize the design of the circuit board, the shell mold, the length of the wire, the specification of the plug, the size of the interface, and the color of the appearance.

Q:How are the products packaged?

A:1. The adapter is placed in a plastic bag and sealed securely.

2. The packaged adapter is placed in a small cardboard box of the right size.

3. Finally, the box is carefully packed in an outer shipping box with padded space to prevent any potential damage during shipping. The model number of the adapter is clearly marked on the outside.
