Collection terminal voltage source conversion device

The utility model relates to the technical field of electric energy data acquisition, in particular to an acquisition terminal voltage source conversion device, which comprises a casing, fixing lugs for mounting the casing are fixed on two sides of the casing, a UPS (uninterrupted power supply), an inverter, a transformer I and a transformer II are mounted in the casing, and the UPS is used for acquiring terminals with different types of working voltages according to different types of working voltages. After the first transformer or the second transformer is selected to be connected, voltage is converted to supply power to the acquisition terminal. The device is simple in structure, the UPS serves as an uninterruptible power supply, power can be provided for the acquisition terminal when a main line stops supplying power, normal use of the acquisition terminal is guaranteed, meanwhile, the UPS of a direct-current power supply can also be used through the inverter, different voltages can be converted through
