Abstract

본 발명은 110V/220V 겸용으로 사용할 수 있는 110V/220V 겸용 변압장치로서, 220V 승압용 변압장치와 110V 감압용 변압장치를 1개의 변압장치로하여 110V/220V 입력 전압에 관계없이 입력되는 전압에 따라 셀렉트 스위치로 조작하여 변압기에 승압 및 감압하여 필요로 하는 출력을 얻을 수 있으며 입력되는 전압을 직접 출력되게 하여 110V 또는 220V 출력전압을 동시에 사용할 수 있어 경제적 이익이 되며 사용상 편리하게 하는 장치이다.The present invention is a 110V / 220V combined transformer that can be used as a 110V / 220V, using a 220V boosting transformer and a 110V pressure reducing transformer as one transformer according to the input voltage regardless of 110V / 220V input voltage It can operate as a select switch to get the required output by boosting and depressurizing the transformer, and it is economically profitable and convenient to use because it can use 110V or 220V output voltage at the same time by directly outputting the input voltage.
