110V和220V工作模式下需要更换保险丝么？
现在里面是500毫安的。。。

谢谢解答~！

翻了一下说明书，原文这么说：
AC POWER INPUT CONNECTOR AND FUSE HOLDER:
The AC power input uses a standard IEC type connector. One USA compatible power cord is included with
DAC1 converters shipped to North America. IEC style power cords in country specific configurations are
available in your locality.
The fuse holder is built into a drawer next to the IEC power connector. The drawer requires two 5 x 20 mm 250 V
Slo-Blo® Type fuses. The drawer includes a voltage selection switch with two settings: “110” and “220”. The fuse
rating for the 110-Volt setting is 0.50 Amps. The fuse rating for the 220-Volt setting is 0.25 Amps.
The AC input has a very wide input voltage range and can operate over a frequency range of 50 to 60 Hz. At
“110”, the DAC1 will operate normally over a range of 90 to 140 VAC. At “220”, the DAC1 will operate normally
over a range of 175 to 285 VAC.
Caution: Always install the correct fuses when changing the voltage setting. Always insure that the voltage
setting is correct for your locality.

110V的是500mA，220V的是250mA。
调转后面保险丝插座方向来同时使用两根保险丝（110V）或使用一根闲置一根（220V）来达到电流减半而输入功率不变的目的。

唉我真是土人...
