Compared to the old generation of 5W-18W KS39DU US/AU/UK/EU/CN/KR plug adaptor series that has been on the market for years, the new generation case has a significant distinction. The main diference lies in its simultaneous compliance with various safety standards such as 62368-1. and 61558-1. as well as additional certifications of CCC / UKCA / SAA(RCM), With the compact profile design, it prevents occupying adiacentoutlets, and flame retardant Pc materia. matte finish, scratch resistant and ant-ingerorint, This ac to dc converter is a high-owality, portable angfully certified wal-mounted green adaptor, ideal for a variety of consumer electronics, led devices, or home application.

lEC 61558 is a series of standards maintained by the lEc Technical Committee (Tc) 96 -"Transformers, Reactors, Power supply Units andCombinations Thereof". Among the many international technical standards aimed at ensuring produc quality and safety,lEc 61558 is important toengineers working with any equipment that contains a transformer or power supply. lEc 61558 protects buyers against unsafe products andenables responsible suppliers to demonstrate acherence to accepted safety orincioles, aking that commitment can ease product certilicationand save time in the test house.lEc 61558 comprises two parts:

61558-2 presents requirements for specific product types

Note that part 2 specifications may include additional or diferent limitations on input and output ratings. All part 1 specifications must be metunless superseded by a part 2 requirement. All products must comply with an applicable part 2.lEC 61558

certification requires compliance with the 61558-1 general requirements and the relevant part 2. if two part 2 conditions applycompliance with both is required.

Various lEc product standards refer to 61558 as a means of ensuring the overall safety of products that contain transformers and/or powelsupplies.some examples include:

• lEC 60335-1 safety of household and similar appliances
• lEC 60204-1 electrical equipment of machines
• lEC 60598-1 luminaires
• lEC 60730-1 automatic electrical controls for household and similar use
• IEC 61347-1 lamp control gear

 

There are 18 part-2 specifications relating to various types of transformers, such as separating transformers, control transformers, isolatingtransformers, and produc-specific applications such as transformers for use in toys, or in the ignition systems of ol and gas burners. switch modepower supplies are covered in parts 2-16. Figure 1 shows these part-2 specifications in relation to the general lEc 61558-1 requirement.
