Tips: How to Solve the Electromagnetic Compatibility of AC Wall Adapter?

Cut off the propagation path of the interference signal to reduce the influence of electromagnetic interference and weaken the signal of electromagnetic interference. The wall mount AC adapter can adopt a filter to filter the interference signal of AC and DC wires. The EMI filter of the power adapter is for AC and DC wires. Both differential mode and common mode interference have a strong suppression and weakening effect. The electromagnetic compatibility of the PCB board of the power adapter is also particularly important.
The PCB board is the most important part of the circuit components and device connections of the power adapter. All parts are connected by the PCB board. The quality of the PCB and component layout design has a great impact on the electromagnetic compatibility of the power adapter. So at the beginning of the design, the anti-interference of the PCB is designed well, and unnecessary actions can be reduced later. The anti-interference design of the PCB mainly includes PCB layout, wiring and grounding, and component layout. Its role is to reduce the electromagnetic radiation of the PCB and the PCB The crosstalk between the upper circuits. In addition, it should be noted that the frequency of the hum frequency caused by the electromagnetic interference of the general transformer is generally about 50HZ, and the hum frequency caused by improper ground wiring is about 100HZ due to the frequency multiplication of the rectifier circuit. It is still detectable.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
