摘要
DC regulated power source apparatus for incorporation in electronic devices which, when equipment such as a sequence controller or numerical control unit for controlling a machine tool is subjected to maintenance or inspection, require that a power source voltage be shifted from a reference voltage by a fixed value. The DC regulated power source apparatus includes a first output voltage adjuster (4) capable of adjusting an output voltage (Vo") to a desired value by means of a rheostat, and a second output voltage adjuster (18, 17) operated after the output voltage (Vo") has been adjusted to the desired value by the first output voltage adjuster, the second output voltage adjuster being capable of shifting the adjusted output voltage (Vo") by a prescribed amount to a value higher (18) or lower (17) than the desired value by simple manual or automatic switching (16, 19 to 23).
