Charger Certification standards

Charger Certification standards

 Charger safety regulations (performance); primary side, secondary side; charger safety regulations (EMC); charger safety regulations; charger EMC; radiation photos; radiation test pictures; conduction; charger safety regulations---- Insulation; charger safety regulations----flame retardancy; efficiency; safety devices; other functions; a. Tension requirements: UL1310 specifies that the AC line is subjected to 35LB relay for 1 minute, the DC line is subjected to tensile force 20LB; EN61558 clearly indicates AC Line 10N pulls while other lines pull 5N. b. Drop (or impact test): UL1310 clearly requires the wall-mounted transformer to be subjected to a drop test. Each product will fall 3 times on the board and the height is 3Ft. For the desktop type transformer, a steel ball impact test is performed. c. Ball pressure test: In the European standard product, the ball pressure test is carried out on the plastic part of the pin. Under the pressure of 20N in the environment of 125 ° C, the diameter of the extrusion mark is less than 2 mm. Basic electrical requirements: a. High voltage test b. Load test c. Overload test d. Short circuit test e. Temperature rise test; Safety gauge for transformer and tube components a. Transformer winding: Safety to Bobbin thickness and resistance Voltage and insulation levels and temperature levels are clearly required. For example, UL1310 requires a thickness of 0.64mm Min, withstand voltage above 1000V, fire rating above 94V2, and temperature resistance CLASS A above 105°C. Only the condition of the rubber compound is described in the safety report, and it is not required to be supplied by any manufacturer. b. Copper wire: Safety regulations have requirements for temperature resistance and insulation grade of copper wire, and detailed records of the number of turns and wire diameters when applying for safety regulations are not allowed to be changed at will, and copper wire production is not determined in the safety report. factory. C. Insulation tape: Safety regulations also require fireproof, pressure-resistant and temperature-resistant insulation tapes, but the safety report generally does not describe this point, so it is also a material that is currently chaotic on the market. d. Thermal fuse: In order to ensure that the product has no high temperature and leakage during abnormal conditions, a temperature fuse is connected in series with the input end of the transformer to ensure the safety of the person and property. The temperature fuse temperature grade is selected according to the short-circuit test required for the insulation level of the product when applying for safety. The model and specification of the thermal fuse are recorded in the safety test report in detail. If the change is required, the safety registration must be re-registered. e. Rectifier components The safety test report records the electrical specifications of the rectifier components, but does not specify the manufacturer. f. Electrolytic Capacitor: The safety test report also records the capacity and withstand voltage of the electrolytic capacitor, but does not stipulate that the manufacturer's g.PCB safety regulations are required for PCB temperature and flame retardancy. For example, UL1310 requires PCB flame retardancy. It is 94V0 grade, so the model and certification number of the PCB are recorded in the test report. Some safety test reports only record the temperature resistance grade and the flame retardant grade, and do not require other requirements. h. Iron core: There is no record of the iron core model in the safety report, as long as the temperature rises through the safety regulations, the most economical core material. i. Plastic Case (Case) Safety regulations have strict regulations on the size, shape, thickness, window size, material, temperature grade and flame retardant grade of the plastic case. Therefore, if the customer requests other appearances, it is basically Report security and take photos in the test report. j.AC power cord: The AC power cord itself has strict safety requirements. Therefore, when the safety application is applied, the AC power cord is required to have relevant safety certification. When the transformer is applied for safety, the AC power supply is recorded in detail in the test report. Manufacturers, specifications, models, can not be replaced at will, need to report safety regulations when replacing AC line. The dimensions of the various parts of the AC PLUG of the AC power cord have corresponding safety regulations.
