ERP 测试中遇到的问题
ERP能效测试中低压外部电源和外部电源是具体怎么区分的呢?2. ‘low voltage external power supply’ means an external
power supply with a nameplate output voltage of less
than 6 volts and a nameplate output current greater than
or equal to 550 milliamperes;
看标准定义 输出电压小于 6V 电流大于550mA的就是低压外部电源, 以外的就是其他 kaiden 发表于 2013-7-5 11:07 static/image/common/back.gif

非常感谢 是的,如果是12V,500mA也不算低電壓外部電源,必須兩者都符合才是 电压小于6Vdc, 电流大于等于550mA
