PURPOSE:To provide a power unit which makes a stable response to control and is flexible. CONSTITUTION:A CPU 5 reads in a voltage Vref corresponding to an input source voltage by a voltage detection and CPU power source part 4 when actuated, and calculates and sets various driving conditions of a transformer T102 on the basis of the voltage. Therefore, the power source can stably be started up irrespectively of whether the input source voltage is high or low, an element which drives the transformer T102 is prevented from being broken, and the device is flexible to the input source voltage. |
