It is connected to the circuit of the device through a rectifier, and forms a DC power supply circuit that prevents high frequency noise with the inductance of the secondary coil.
A power supply characterized in that when a plug is inserted into a power jack and current is supplied from an AC power supply, the switch cuts off the connection from the DC power supply and switches the secondary coil of the power transformer to the rectifier circuit side, forming an AC power supply circuit. circuit.
