1. Product marking is incomplete or irregular
The industrial power supply label should contain important information to guide the user in the correct installation and use. The correct labeling of the product is one of the basic measures to ensure the safety of the user's personal property. Marking is required to be durable and eye-catching. After normal use, the mark should not fall off, and the content should be clean and legible. Products sold in China are required to be identified in simplified Chinese characters, and at least the following information should be included: the name, trademark, or identification mark of the manufacturer or distributor; model code or model specifications; power supply properties; If the information is incomplete and cannot be used to properly guide consumers, some may even misuse and damage the electronic equipment connected to it. Common problems are no Chinese logo, no factory name or trademark, model code or model specifications.
2. The power plug is not standardized
China stipulates that household single-phase power plugs have two types of non-grounding and two-poles with grounding. The power plugs shown should prevent unipolar insertion in use, that is, when any one of the plugs of the plug is mated with the live plug of the socket, Other pins must not be easily accessible. In the spot check, it is found that there is a phenomenon that the plug is too long, and the length of the plug increases the risk of electric shock during the plugging process. In addition, the shape of the power plug does not meet the requirements is more common. Because these plugs are not compatible with the sockets used in our country, it is very easy to cause electric shock to users.
3． Fever under normal working conditions is not satisfactory
The role of the power adapter is to convert the voltage. During the voltage conversion process, due to the loss, it needs to consume part of the electrical energy. After the electrical energy is converted into thermal energy, some of the thermal energy is radiated to the surrounding environment through radiation, convection and conduction. Absorption causes the temperature of the power adapter to rise. The rule of heat resistance of insulating materials shows that increasing the internal temperature of the equipment to a certain temperature will cause rapid aging of the insulating materials, shorten the test life of the product, and cause a reduction in safety performance. Therefore, only when the temperature of the power adapter is controlled within a proper range during normal work can it be guaranteed to work safely and normally.
