Standby electric power cutoff apparatus for electronic product

Abstract

A standby electric power cutoff apparatus for an electronic product is disclosed. A power supply/cutoff unit () of the present invention comprises: a power switch (SW) for manually turning an input of an AC power source of the electronic product on/off; a pair of photo-triacs () which are disposed in parallel to each other between input terminals of the AC power source, and which receive power through the power switch (SW); a photo-coupler () which is disposed between the power switch (SW) and the input terminals on one side of the AC power source and comprises a light emitting diode (D) and a transistor (Q) for receiving a light emitting signal from the light emitting diode; and a relay means which comprises a relay (K) connected to a control unit () having a microcomputer (u-COM), and which supplies or cuts off the AC supply power to a power supply unit () by controlling operations for connecting or disconnecting contact points of the relay according to a control state of the control unit (). In addition, a standby electric power cutoff apparatus for an electronic product () which controls functions using a remote controller (). A power supply/cutoff unit (), according to the present invention, comprises: IR-receiving triacs () which receive IR signals from the remote controller, and which are turned on so as to transfer the AC supply power to a power supply unit () when the IR signals are received; and an IR-receiving unit () for receiving the IR signals and transferring the received IR signals as control signals to a control unit ().
