In October 2021, the State Council issued the "National Standardization Development Outline", which requires that by 2025, it is necessary to realize the transformation of standard supply from government-led to both government and market, vigorously develop group standards, and implement the group standard training plan. Huntkey Group actively responds to the national call and leads the industry in the formulation of power industry group standards. On March 15, 2022, the China Power Supply Society announced 16 group standards that have been approved in 2022, including the "Technical Specifications for Energy Efficiency Levels of Switching Power Supply" and "Technical Specifications for Environmental Adaptability of DC Cooling Fans" , "General Technical Specification for DC Cooling Fan Performance", "DC Cooling Fan Operating Life Test Method" promoted by Huntkey Groupand other four standards.





Technical Specifications for Energy Efficiency Levels of Switching Power Supply

Power conversion efficiency, standby power consumption, etc.


Technical Specifications for Environmental Adaptability of DC Cooling Fans

Fan temperature environment, etc.


General Technical Specification for DC Cooling Fan Performance

Fan performance signals, etc.


DC Cooling Fan Operating Life Test Method

Cooling fan operating life, etc.

Improve the standardization for green development, and improve the standard level with scientific and technological innovation. Huntkey Group, relying on its own R&D and design innovation capabilities and the advantages of advanced testing and testing equipment, actively promotes the development of the power supply industry to a higher standard. The draft version of the National Mandatory Energy Efficiency Standard "Technical Specifications for Energy Efficiency Levels of Switching Power Supplies" approved this time defines external power supplies including PD fast charging and adapters, and embedded power supplies including PC computer power supplies, server power supplies, industrial power supplies and other products. The output form of the product is expanded from single output to multiple output. PC power supply and server power supply include redundant applications and non-redundant applications. In a word, this standard not only makes the power product categories included in the national mandatory energy efficiency evaluation more complete, but also raises the severity of the conversion efficiency and standby power consumption of the energy efficiency evaluation grade indicators to a higher level.

The switching power supply is a product that converts alternating current into direct current. The higher the conversion efficiency of the product with the same power, the lower the power consumption of the grid. For example, a low conversion efficiency power supply consumes 1 kWh of electricity when working, while a high-efficiency power supply with the same power only consumes 0.8 kWh of electricity in the same time, thereby indirectly reducing carbon emissions in the air. Huntkey Group's high-efficiency products are mainly achieved through circuit design innovations, such as planar transformer technology, and the application of low-loss devices such as gallium nitride to reduce the self-heating of the power supply. We optimize the power supply industry upgrade through our own technological innovation, improve the industry product evaluation standards, and guide the development of products to higher conversion efficiency and lower standby power consumption. Huntkey Group uses practical actions to help the realization of the national "double carbon" goal.
