Abstract
The utility model relates to a current sampling apparatus, comprising a current sampling board and a large-power current board. The current sampling board and the large-power current board are connected by a board-to-board connector. The large-power current board is provided with a first connector for connecting a work power supply and realizing current input. The current sampling board is further provided with a second connector for outputting acquired weak current signals to a CPU. The beneficial effects are that the current sampling apparatus has a simple structure that the current sampling board and the large-power current board are arranged on a PCB substrate; the apparatus meets an IEC standard while the structure of the apparatus is small and exquisite; the apparatus can replace a current sensor perfectly; and the apparatus is wide in current sampling range, high in precision, and low in price.
