The following is the recommended power supply for the AC-2.
Note that connecting an AC adaptor from other manufacturers may cause a malfunction. Be sure to use the designated AC adaptor.
The AC-2 has a current draw of 18 mA, so it can be used with any type of PSA adaptor (output 200-500mA). However, the PSA series has variations in the plug shape depending on the voltage of the sales region. Please use the model suitable for your region.
