1. a power supply adaptor, it is characterised in that include communication interface, isolating transformer, output filter circuit, voltage-tracingWith control circuit, main control module, current potential adjusting module, current detection module, voltage detection module and output switch module, itsIn,Described current potential adjusting module, drives described voltage-tracing and control for the control signal sent according to described main control moduleThe output voltage of described isolating transformer is adjusted by circuit;

  • Described current detection module and described voltage detection module, be used for the output electric current to described power supply adaptor and output electricityPressure detects;

    Described output switch module, opens or closes described power supply for the switch controlling signal sent according to described main control moduleThe unidirectional current output of adapter;

    According to described current detection signal, described main control module, for judging whether the output electric current of described power supply adaptor is more thanCurrent threshold, and judge whether the output voltage of described power supply adaptor is more than voltage threshold according to described voltage detection signal,If described output electric current is more than described voltage threshold, the most described master control more than described current threshold and/or described output voltageModule controls described output switch module and closes the unidirectional current output of described power supply adaptor.
