Power adaptor for equipment debugging on site

The utility model relates to a power adaptor for equipment debugging on site, which belongs to the technical field of power sources. The power adaptor comprises an input interface matched with a power interface, and a live line and a zero line of the input interface are connected with input interfaces of an alternating current-direct current power convertor and an isolating transformer respectively through a switch control device. Output ends of the alternating current-direct current power convertor and the isolating transformer are electrically connected with an alternating-current output interface and a direct-current output interface of on-site equipment (such as a video camera) to be debugged respectively. When used on site, the power adaptor can be conveniently controlled through the switch control device by connecting the input interface with the power interface, the output interfaces matched with the equipment to be debugged can be powered and power sources for equipment on site can be output simultane
