DoE Ⅵ level for switching power suppy

People on the energy saving and environmental protection requirements are increasingly high, power adapter, switching power, charger and other external power supply as efficient, energy-saving products are also in this plan. The EU is independently promoting the voluntary and mandatory plans of the external power (power adapter, switching power supply, charger) to further improve the energy efficiency requirements of external power (power adapter, switching power supply, charger). And the U.S. Department of energy (DoE) is also in the 2013 released a proposed rule making the announcement (NOPR), the main focus of this standard: power adapter, switching power supply, the charger is the energy saving standard VI DoE.
EU V5 CoC standards:
The EU is independent of the external power to promote the voluntary and mandatory plans to further improve the external power (power adapter, switching power, charger and other external power supply) of energy efficiency requirements. At present, the mandatory requirements for the external power supply of the EU 278/2009 ErP. The EU released the draft of external power energy efficiency behavior standards V5 CoC in 2013.3 months to further improve the power supply (including power adapter, switching power, charger and other external power supply) of the energy efficiency requirements standards. The efficiency and load power requirements of the new CoC voluntary guidelines are higher than the current ErP eco design requirements, but it is lower than the current draft of the U.S. Department of energy. The efficiency requirements of the CoC guidelines are added to the efficiency of the 10% load conditions in order to ensure the efficiency of certain applications. Where the first phase of the proposed effective date is January 1, 2014, the second phase of the proposed effective date for January 1, 2016.

United States VI DoE (six level energy efficiency) standards:
The U.S. Department of energy (DoE) is also in the 2013 released a proposed rule to develop the announcement (NOPR), the main target: battery charger with the external power of the energy saving standard is VI DoE. The standard power supply includes an external power supply (BCS) and / or an external power supply (EPS), which includes a battery charging system () and / or an external power supply (), which is defined in the regulations, or is an increase in the number of constraints, or is becoming more stringent in the existing limits. Any charge product or external power supply (EPS) will be within the scope of this ordinance. The regulations include: providing products corresponding to the label, and most likely required to register on the U.S. Department of energy (DoE) website. It is reported to be effective in July 1, 2013. We will detail the specific requirements of the EU V5 CoC and VI DoE, please pay attention to the news that we have released. In line with the EU V5 CoC and the United States VI DoE six energy efficiency part of the product.
