备注(note) |
1. 以上数据除特殊说明外，都是在TA=25oC,湿度<75%,输入标称电压230Vac和输出额定负载时测得；( All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature) |
|||||
|
2. 纹波与噪声是使用300mm的双绞线，同时终端并联一个0.1uF的高频陶瓷电容和一个47uF的电解电容测得的。( Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor) |
||||||
|
3. 电源在系统内是被视为元器件，需结合终端设备进行电磁兼容相关确认.( The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. ) |
