PROBLEM TO BE SOLVED: To continuously supply a low-voltage power to an exterior unit by a constant output voltage or a constant load input voltage regardless of load capacity, load fluctuation, or the like by continuously detecting the output voltage, and by continuously outputting a constant voltage according to the detected voltage. SOLUTION: In a low voltage/supply, a control circuit 1 constantly detects an output voltage and generates a rated output voltage correction instruction when a voltage drops at least for a specific level when an output voltage drops according to the detection output voltage, for example, when the operation of a load fluctuates. Then, the rated output voltage correction instruction is sent to an output stabilization circuit 2, a switching circuit 5 is controlled according to the instruction signal, and the rated output voltage is corrected, for example, by increasing the rated output voltage by the voltage drop, thus outputting a constant voltage without causing the output voltage drop to be suppressed constantly without being affected by load capacity and load fluctuation. |
