Claim 2:
3. The self-service apparatus of claim 2, wherein the voltage converter comprises a DC voltage conversion chip and an adjustable voltage divider,
wherein the DC voltage conversion chip has a voltage output terminal and a voltage sensing terminal, and adjusts a magnitude of the multiple DC voltage outputs according to a magnitude of a sensing voltage received at the voltage sensing terminal, and
wherein the adjustable voltage divider has high level and low level terminals which are connected to the voltage output terminal and ground respectively, and the adjustable voltage divider has an adjustable voltage terminal which is connected to the voltage sensing terminal, to change the magnitude of the sensing voltage and further change the magnitude of the multiple DC voltage outputs by adjusting a voltage division ratio of the adjustable voltage divider.
