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 sec ) to a desired value by means of a rheostat, and a second output voltage adjuster (18, 17) operated after the output voltage (Vo sec ) 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 sec ) 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).
