The power supply market in ChinaThe power supply market in China
¾ The saleroom of the AC/DC power supplies in China is about US$723 millions in China
¾ About 60％ of the total market share ¾ The increase rate in 2002-2007 will be 12.4％
¾ About 39.1% of the power supplies are external power supplies due to the low labor-cost and the main suppliers for the mobile-phones, laptops and other movable consume electron products are transferred into China

energy savings & environment effectsenergy savings & environment effects
¾The efficient design can save 15％～20％ energy ¾The stock of the power supplies is
increased rapidly ¾The most power plants in China use the
fossil fuel

Barriers for the EE power supplies promotionBarriers for the EE power supplies promotion
The energy-efficient power supply has more advantages such as small size, low weight, low operating temperature, high reliability and etc. but it still has some market barriers: ¾ The purchaser of the power supplies isn’t the end-user,
needn’t pay for the electrical bills and is not the direct beneficiary for energy savings.
¾ A consumer normally buys a complete set of product rather than an individual power supply
¾ There has not related information to support the consumer find an energy efficiency power supply，
¾ The drastically market competing and the reducing profit rate

CECP technical specificationCECP technical specification
¾ The specification is based on the measurement on the 800 products in China, US and Australia
¾ Been composed by two parts: • The average efficiency in the active model • The no load power
¾ The products must meet both the two parts ¾ The products must be tested according to the
procedure provided in the specification
