![]() ![]() This definition comes from ITE/AV product (IEC/EN/UL 62368-1).Ĭlass 2: When an electronic circuit is powered by class 2, its output current and power are under the limitation shown in UL 1310 Table 30.1, and the risk of fire can be reduced significantly. Therefore, the plastic enclosure of these power supplies could use HB flammability rating to reduce cost. So, the safety distances and flammability rating of components can be much lower. LPS: When an electronic circuit is powered by a limit power source (LPS), its output current and power are under the limitation shown in IEC 62368-1 Table Q1, and the risk of fire can be reduced significantly. This means a class II SPS does NOT have a terminal/pin for earth ground connection. This means a class I SPS will provide a terminal/pin for earth ground connection.Ĭlass II: Equipment in which protection against electric shock does not rely on basic insulation only, but in which additional safety precautions, such as double insulation or reinforced insulation are provided, there being no reliance on either protective earth or installation conditions. For example, LED power supply will require that it should be normally burned for 200 hours under TC environment to ensure the suitability of TC declaration.Ĭlass I: Equipment where protection against electric shock is achieved by using basic insulation and also providing a means of connecting to the protective earth conductor in the building where by routing those conductive parts that are otherwise capable of assuming hazardous voltages to earth ground if the basic insulation fails. The difference between ENEC and TUV for LED power supply is that ENEC should also meet the requirements of performance EN 62384 in addition to the safety regulations EN 61347-1 and EN 6. For example,ENEC05 represents the ENEC logo issued by DEKRA, and ENEC17 represents the ENEC logo issued by TUV RH. The code of verification unit will be added after the ENEC mark. The new generation LED power of MEAN WELL have apllied for the ENEC mark presently. ENEC is a more competitive enterprise High value reliable verification mark. With the efforts of European industrial and consumer organizations, the scope of application has covered lighting products and their accessories, switches, controllers, connectors, couplers, plugs, consumer electronic products, audio-visual equipment, information technology equipment, household appliances, safety isolation transformers, electrical appliances, filters and other products. At the beginning, it was only applicable to all kinds of lamps and lanterns. ![]() There are 24 member certification bodies including TUV, VDE, Demko, Nemko participating in the scheme. ![]() The scheme is based on the European full certification scheme of ISO-type5, which was initially established in 1991. ENEC is the European safety standard mark. ![]()
