High-precision constant-current numerical control electronic load and working method thereof

The invention relates to a high-precision numerical control constant-current electronic load and a working method thereof. The high-precision numerical control constant-current electronic load comprises a processor and a constant-current electronic load body; the constant-current electronic load body is powered by a detected power source, and electrically connected with the processor, and is suitable for conducting constant-current output under control of the processor; and the processor is suitable for detecting an output current and voltage of the constant-current electronic load body and adjusting constant-current output according to an obtained current signal to enable an output power source of the constant-current electronic load body to have the constant current. Constant-current output of the constant-current electronic load body is subjected to closed-loop control, thus the current precision is improved, and the detecting precision of the detected power source is improved. 本发明涉及一种高精度数控恒流电子负载及其工作方法，其中，
