description The application provides an electric energy meter comprising an AC/DC converter, an AC side is connected to commercial power, a DC side is connected to a plurality of function modules, and the AC/DC converter is used for providing direct current for each function module; the detection circuit is connected to the power supply access of each functional module and is used for detecting the power supply of each functional module; the control circuit comprises a plurality of control branches and a plurality of first switching devices in one-to-one correspondence with the control branches, each functional module corresponds to one first switching device, and each first switching device is arranged on a power supply path of the corresponding functional module and used for controlling on-off of the power supply path. The control branch is connected with the control end of the first switching device and is used for controlling the opening and closing of the first switching device; and the controller is respectively co
