Abstract:
1. A substrate comprising: a plurality of input ends, between any two of which an alternating voltage is applied; a plurality of output ends; first and second direct-current power lines; a first region permitting mounting of any one of a plurality of kinds of first surface-mount devices that selectively establish electrical continuity between one of said plurality of input ends and either said first or said second direct-current power line; a second region permitting mounting of a second surface-mount device that selectively establish electrical continuity between one of said plurality of output ends and either said first or said second direct-current power line; a first terminal provided on said first direct-current power line; a second terminal provided on said second direct-current power line; a third terminal provided between said first terminal and said second terminal, said first and second terminals and/or said second and third terminals being connected to a smoothing capacitor, and terminals between which said smoothing capacitor is not connected being connected to a jumper.
