Power adapter CE certification standards and certification fees

Brief introduction and structure of the power adapter:

Components of the power adapter:

Shell, power transformer, rectifier circuit

Power adapter supporting objects:

Telephone handsets, game consoles and other equipment

The power adapter is classified by output:

AC output type and DC output type

Power adapter adapter products:

Telephone handsets, game consoles, language repeaters, walkmans, notebook computers, and some small household electrical appliances and leisure products, etc.

Power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is widely used in mobile phone handsets, game consoles, language repeaters, walkmans, notebook computers, cellular phones and other equipment. The power adapter is generally composed of a shell, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection mode, it can be divided into wall type and desktop type. Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation and other fields. ISO certification

Since power adapters are widely used, their safety requirements are also relatively high. Typically, the EU CE certification is required by the CE certification body. In fact, the EU CE certification program is also a relatively simple certification, and the price is not outrageous, but the specific certification The cost also depends on the certified power adapter product, the selected CE certification body and the relevant EU CE testing directives, and it is also related to different test items.

Different product test items are also completely different. Generally, common products are electronic and electrical products, and common test items are classified into EMC and LVD directives. Common test items are classified into EMC and LVD directives. The following takes the AC input power adapter as an example to explain the CE test items:

Adopt EMI standard

EN55022

Radiation + Conduct

EN61000-3-2

EN61000-3-3

EN55024 (EMS test item):

EN61000-3-2 Current Harmonic

EN61000-3-3 Voltage Flicker/Fluctuation

EN61000-4-2 ESD electrostatic discharge test

EN61000-4-3 RS radiated immunity

EN61000-4-4 EFT fast burst

EN61000-4-5 SURGE lightning strike

EN61000-4-6 C/S conducted immunity

EN61000-4-8 M/S power frequency magnetic field

EN61000-4-11 DIPS voltage transient immunity

EN61000-3-2 Current Harmonic (The output power of the power adapter is greater than 75W and needs to be tested, and there is no applicable limit value for less than or equal to 75W, and no test is required)

The cost of CE certification for power adapters is related to different test items and the number of test items. The price of CE certification is also related to the issuing agency. In addition, one thing to note is whether the power adapter needs a factory audit fee? In fact, many certification projects require factory audit fees, which are an important part of certification costs. However, CE certification only needs to test the product itself and will not involve the factory audit process, so there is no need for factory audit fees. In addition, CE certification is a one-time fee, and no other follow-up costs will be incurred. If you are a power adapter manufacturer and plan to export to the EU market, then it must be right to find our BCTC double test for this CE certification. Electromagnetic compatibility test
