Hello,

if you have been using it so far without problems in US I suppose that the
supply marked 230V has been modified for 115V but the mark remained
unchanged.
In the A-100 section of our FAQ page you find details how to modify the
older supplies for other mains voltages (or how to find out for which mains
voltage the supply has been manufactured or modified):

"Modification of the A-100 power supplies A-100NT12 and A-100PSU2 for
another mains voltage (English, for qualified persons only)"

Best wishes
