Californian Energy Star CEC Detection

California Energy Council's energy efficiency test.
The 58 types of products sold in California require CEC product energy efficiency certification, mainly for rice cookers, power supplies, and lamps(ballasts or energy-saving lamps). The sales of 58 types of electronic and electrical products in California require CEC energy efficiency certification. The regulations are specifically divided into energy efficiency indicator requirements, measurement methods, and phased implementation plans.
For AC Input Power Supply for AC Input Input, the California Energy Act stipulates that such sales in California need to be CEC before July 1, 2007. Energy efficiency test certification, If the application device can not meet the requirements of the new application specification, it is prohibited to sell it in California.
This energy bill has special requirements for the performance of switching power supplies. It has two levels of "III" and "IV", that is, third and fourth grades. It requires higher power consumption and overall efficiency for switching power supplies.:

     The implementation of the power supply device is divided into two phases:
The first phase will be implemented from July 1, 2007. Level III requirements(applicable to 2007-7-1 to 2008-7-1):
铭牌输出
最小能效值
0~1W
0.49*铭牌额定输出
1~49W
0.09Ln铭牌额定输出+0.49
≥49W
0.84
 
 
 
空载最大消耗功率
0~10W
0.5W
10~250W
