Abstract
본 발명은 전압전환 경보장치에 관한 것으로, 교류전원을 입력받아 직류전원으로 변환하고 정류하여 출력하는 전원입력부와, 상기 전원입력부에서 출력된 전압을 충전하는 전압충전부와, 상기 전압충전부에서 충전된 전압의 인가를 스위칭하는 스위칭 트랜지스터와, 상기 스위칭 트랜지스터의 스위칭 상태에 따라 여자되는 트랜스포머와, 상기 트랜스포머의 2차측 코일에 여자된 전압을 정류시킨 후 부하에 공급하는 전압출력부를 구비하는 전원공급장치에 있어서, 상기 전원입력부의 출력단에 접속되어 인가되는 전압을 감지하여 부하측에 전원의 인가를 제어하는 전압전환감지부와, 상기 전압전환감지부에서 출력된 전압을 인가받아 경보음을 발생하는 경보장치를 구비하여 정격전압이 110V로 설정되어 있는 각종 전자기기에 설정되어 있는 정격 전압 보다 높은 전압이 인가되면 자동으로 경보를 수행함과 동시에 공급전원을 차단시키는 것이다.The present invention relates to a voltage switching alarm device, the power input unit for receiving the AC power is converted to DC power, rectified and output, a voltage charging unit for charging the voltage output from the power input unit, the voltage charged in the voltage charging unit A power supply comprising a switching transistor for switching the application of a voltage, a transformer excited according to the switching state of the switching transistor, and a voltage output unit for rectifying the voltage excited by the secondary coil of the transformer and supplying it to a load. And a voltage change detection unit for controlling the application of power to the load side by sensing a voltage applied to the output terminal of the power input unit, and an alarm device for generating an alarm sound by receiving the voltage output from the voltage change detection unit. Rated voltage set in various electronic devices with the rated voltage of 110V When a voltage higher than the voltage is applied, it automatically alarms and cuts off the power supply.
