What are the common quality problems with the powe


1. The heating under normal working conditions does not meet the requirements

The high temperature rise of the power adapter under normal working conditions is a common problem. Power adapter shell temperature and the difference between the ambient temperature should not exceed 60 ℃, even in the hot summer temperature reaches 35 ℃, the shell temperature can't over 95 ℃, if found the product temperature is too high we should stop using in time.

2. Safety performance of products in short circuit and overload.

In the fault condition of short circuit of output, capacitor or diode, the internal loss of power adapter increases sharply, leading to the increase of temperature in each part

3, the products are not complete or non-standard marking shall contain important information guide users install and use right, the right label product tags to ensure that users of personal property safety.

4. The power plug is not standard

In China, there are two types of single-phase power plug with two levels without polar and two-stage grounding. The power plug should be used to prevent single stage insertion.

The power adapter is prescribed by the state for the 3 c certification of products, quality appeal quality problems, mainly is the partial enterprise safety standards is a lack of comprehensive, accurate understanding and the understanding, design and product structure is unreasonable, in order to reduce the finished product to cut corners, this is the important cause of part of the product is unqualified. And electronic technology co., LTD. Shenzhen yongle connected power adapter products are produced in the 3 c certification, the company set up an independent quality assurance department, and according to the pass, 2000 to establish quality management system, some products have UL, FCC, CE, CCC, SAA, SGS, MEPS, CEC, and other product certification authority.
