Power adapter ROHS certification——ZRLK

Power adapter, also called external power supply, is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shell, transformer, inductor, capacitor, control IC, PCB board and other components. The working principle of the power adapter is from AC input to DC output; According to the connection mode, it can be divided into wall type and desktop type, which are commonly used in small electronic products such as mobile phones, LCD monitors and laptops.

Power adapters are widely used, such as refrigerators, washing machines, air purifiers, etc. In addition to these things that we can touch daily, it is also applied to some products that we are easy to ignore, such as LED lights and lighting equipment in our home, digital cameras, routers, laptops, and so on. However, RoHS certification is generally required for the power adapter to be exported to the EU market.

What is RoHS certification?

RoHS certification is a mandatory standard formulated by EU legislation. Its full name is Restriction of Hazardous Substances. This standard has been officially implemented since July 1, 2006. It is mainly used to regulate the material and process standards of electronic and electrical products, making them more conducive to human health and environmental protection.
