The purpose of the present invention is to provide a power-saving-type power supply device having a double sensing module which can sense the maximum power saving and prevent a malfunction of the power supply device by enabling a control unit to perform more accurate operation control through a structure in which double sensing modules for sensing a power saving mode determination signal are installed. The power-saving-type power supply device reduces consumption of standby power and comprises: a first sensing module which detects operation of a standby module, which receives commercial power and supplies standby power to a load, and outputs an on/off signal according to the detected operation; a second sensing module which detects operation of an operation module, which supplies operation power to the load, and outputs an on/off signal according to the detected operation; the control unit which detects the on/off signal of at least one from the first sensing module or the second sensing module and outputs a switching control signal according to the detected on/off signal; and a switching device which is installed between the standby module and the load and operates to cut electrical connection between the standby module and the load according to the switching control signal output from the control unit. Therefore, the maximum power saving can be sensed and a malfunction of the power supply device can be prevented by enabling the control unit to perform more accurate operation control through the structure in which the double sensing modules for sensing the power saving mode determination signal are installed. |
