1.  SCOPE                                            
  The document detail the electrical,mechanical and environmental specifications of a SMPS,                                            
  the power supply provide 12W continuous output power.                                            
  资料详细描述了一款12W(连续输出功率)开关电源的电气性,结构性及环境等要求。     
                                              
2.  INPUT FEATURE/输入特性:                                            
 2.1  RATED INPUT VOLTAGE:100Vac to 240Vac.  额定输入电压范围从100Vac到240Vac.                                           
   INPUT VOLTAGE RANGE: 90Vac to 264Vac.  输入电压范围从90Vac到264Vac.                                           
 2.2  RATED INPUT FREQUENCY: 50/60Hz.  额定输入频率50/60Hz.                                           
   INPUT FREQUENCY RANGE: 47Hz to 63Hz. 输入频率范围从47Hz到63Hz.                                           
 2.3  INPUT CURRENT: 0.4A max. at 100-240Vac.  最大输入电流0.4A(输入条件100-240Vac).                                           
 2.4  INRUSH CURRENT: 40A max. at 100-240Vac input for a cold start at 25℃.                                           
   在冷开机条件下,最大浪涌电流不超过40A(输入条件100-240Vac).                                           
 2.5  AVERAGE EFFICIENCY: More than 75% at 110/220Vac input and output full load.                                           
   平均效率高于75%(输入110/220Vac和输出满载条件).                                           
 2.6  Energy Consumption/空载功耗                                           
   在额定输入100-240V时,空载功耗≦0.3W                                           
                                              
3.  OUTPUT FEATURE/输出特性:                                            
 3.1  Static Output Characteristics<Vo&R+N>静态输出特性                                           
   Output    Rated Load/额定负载          Output Range        Ripple&Noise       Remark              
   Rate     Min.Load      Max.Load     输出电压范围        纹声与噪音       备注              
   +12V    0.0A     1A     11.4-12.6V        120mVpp                      
                                                                                             
R&N:Measurement is done by 20MHz bandwidth oscilloscope and the output paralleled a 0.1uF ceramic                                              
 capacitor and a47uF electolysis capacitor.(test underthe condition of rated input and rated output)                                              
纹波与噪音:量测时示波器选用20MHz带宽限制,输出端要并联一颗0.1uF的陶瓷电容和                                              
一颗47uF的电解电容.(在额定输入及输出的条件下检测)
