Introduction - If you have any usage issues, please Google them yourself
This simple device consists of single-chip power quality detection control module, power module, signal conversion and processing module and other accessories. c8051F020 for the host microcontroller, it can accurately complete all the way while the frequency of alternating current frequency, voltage rms, current rms, active power, reactive power, power factor and other measurements. Software for real-time sampling the input voltage signal. System debugging, use the function generator output voltage signal as a sinusoidal voltage signal input AC signal, the voltage signal by the move made after the representatives of the same circuit with the circuit input signals.
