APPARATO DI ALIMENTAZIONE PER UN APPARECCHIO ELETTRICO.

摘要

A power supply apparatus includes a power supply circuit and a power-on circuit. The power-on circuit detects a remotely transmitted control signal and causes a transition of the power supply circuit to a turned on state. The power-on circuit includes a transducer configured to provide a power-on signal in response to the remote control signal. The transducer triggers transition to the turned on state through a switch driven by the power-on signal output from the transducer and arranged to supply a power supply circuit enable signal. A DC blocking capacitor is connected between an output of the transducer and a control terminal of the switch.
