High-quality power supply generally has many national certification marks, such as FCC, UL of the United States, China Great Wall and so on. These certifications are professional standards for power supply formulated by certification bodies according to technical specifications in the industry, including production technology, electromagnetic interference and safety protection. All products that meet certain indicators can only use the certification mark on the packaging and product surface after passing the certification declaration, which has certain authority.

Special power supply:
Special power supply can be subdivided into: shore power supply, security power supply, high-voltage power supply, medical power supply, military power supply, aerospace power supply, laser power supply and other special power supplies.
Special power supply is a kind of special power supply. The so-called special is mainly because the technical index requirements of measuring power supply are different from ordinary power supply, mainly because the output voltage and current are extremely high, or the stability, dynamic response and ripple are extremely high, or the output voltage or current of power supply is required to be pulse or other requirements.
This makes the design and production of this kind of power supply have more special and even stricter requirements than ordinary power supply. Dedicated power supply is generally designed for special loads or occasions and is widely used. It mainly includes electroplating electrolysis, anodic oxidation, induction heating, medical equipment, power operation, power test, environmental protection dust removal, air purification, food sterilization, laser infrared, photoelectric display and so on.
