Like AC, DC can be at any voltage.
The switching of the circuitry is done internally for the different voltages. This is done when you move the switch on the front of the meter from AC to DC.
+ and - voltages not connected to earth
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.

A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
On the side of the relay there is a name plate that tells you the current carrying capacity of the contacts. It gives you the ratings at different AC voltages and a DC rating of the contacts at different voltages.

DC (dirrect current) electricity is not used in homes, because different appliances (lamps, TVs, etc.) use different voltages. By using AC electricity, each appliance can take the voltage it needs. If we used DC, some smaller appliances would constantly burn out, because the voltages are far too high.
none, no modulation variations occur.
It means they come in different voltages to supply power to different things that require different voltages.
