<p>PROBLEM TO BE SOLVED: To provide a control voltage supply device which makes an output voltage of its power supply source changeable according to an instruction signal from a control part and reduction of its standby power consumption. SOLUTION: The control voltage supply device is constituted of a control part 1 which supplies each load a control voltage and a power supply source 2 which supplies the control part the control voltage. The power supply source has an automatic voltage control part which automatically controls the output voltage to an required voltage and a voltage change part which changes the required voltage according to the instruction signal, and the control part has a variable means 11 which generates the instruction signal to change the required voltage.</p> |
