ボリュウム簡易設定装置。A semiconductor chopper that controls the output of a DC power supply, a sense resistor that detects the amount of change in the resistance value of the load, a comparator that controls the semiconductor chopper by comparing the voltage value of the sense resistor with a reference voltage, and a comparator that controls the semiconductor chopper by comparing the voltage value of the sense resistor with a reference voltage. In a constant current drive circuit having a volume for varying a reference voltage, a through hole is bored in the outer box housing the constant current drive circuit, and the operation part of the volume is placed in the through hole so that the operation part of the volume is exposed to the outside. A table with the optimum current values for each type of load is created, and selection markings are written around the through hole so that the volume can be adjusted to the optimum current value listed in the table.
