The power switch is used to control the switch tube through the circuit to conduct high-speed pass and cut off, convert the direct current into high-frequency alternating current and supply it to the transformer for transformation, thereby generating the required one or more sets of voltages. However, in general, RoHS certification is required for such electronic and electrical products to be exported to the EU market.
What is RoHS certification?
RoHS certification is also called environmental certification, which is in line with European and American standards. It is the abbreviation of "The restriction of the use of certain hazardous substances in electrical and electronic equipment" (The restriction of the use of certain hazardous substances in electrical and electronic equipment). Imports of harmful heavy metals such as cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated diphenyl ethers PBDE and polybrominated biphenyls PBB have been banned by the EU from July 1, 2006.
ROHS certification mainly involves products
RoHS targets all electrical and electronic products that may contain the above six hazardous substances in the production process and raw materials, mainly including: white appliances, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc., and black appliances, such as audio and video products. , DVD, CD, TV receiver, IT products, digital products, communication products, etc.; electric tools, electric electronic toys, medical electrical equipment, etc.
Switching power supply RoHS test items
1. Lead (Pb)
2. Cadmium (Cd)
3. Mercury (Hg)
4. Hexavalent chromium (Cr6+)
5. Polybrominated biphenyls (PBBs)
6. Polybrominated diphenyl ethers (PBDEs)
7. Diisobutyl phthalate (DIBP)
8. Phthalic acid (2-ethylhexyl ester) (DEHP)
9. Dibutyl phthalate (DBP)
10. Butyl benzyl phthalate (BBP)
Switching power supply RoHS inspection process
1. Project application-submit a test application to ZRLK testing agency.
2. Document preparation-according to the testing requirements, the company prepares relevant documents.
3. Product testing-the company sends the samples to be tested to the laboratory for testing.
4. Preparation of reports-certification engineers prepare reports based on the qualified test data.
5. Submit for review-the engineer will review the complete report.
6. Issuing a certificate-after the verification is correct, a certificate will be issued.
