It’s recommended that you use the original power adaptor that came with the Famicom, Disk System and accessories when playing in the United States or Canada. To do so will require a step-down converter.
The Disk System power adaptor is equipped with the same prongs, nearly the same input voltage (AC 100V), and the proper output voltage (DC9V) as power adaptors used in the United States and Canada.

It has a DC 9V voltage regulator. The voltage regulator needs at least DC 9V or above to operate. (The limit is likely DC 12V.) You can figure this out by multiplying the voltage of the C battery by the number of batteries required: DC 1.5V x 6 = DC 9V. The Disk System adaptor is center negative. Adaptors in the U.S. and Canada are usually set to positive. The key is the amp rating. Your amp rating has to be at least 850mA.
So, you can use any adaptor in which:
1. The center tip can be changed to negative.
2. The voltage can be set to DC 9V.
3. The amp rating at least 400mA.
The original FDS adapter is DC 9V, but the voltage regulator can handle DC 9-12V.
To prevent from overheating and damaging your Disk System, it is recommended that you use a step-down converter. Japanese electrical outlets output 100V, which is what the Disk System power adaptor is made to receive. United States and Canadian electrical outlets output 120V. Step-down converters that will convert the electrical outlet output to 100V are available online and in stores.
