The product is a rail type multi-loop power meter,including MCU module and power module, including metering module,current module and voltage input module. The current input module and voltage input module respectively input four current signals and one processes the received current signal and the voltage signal and outputs the signal to the MCU module.The product can monitor 12 output loops, whitch is convenient for counting the power consumption of each loop.

Multi-loop power meter, which can measure the grid parameters of 4 three-phase or 12 single-phase loops, including voltage, current, power, frequency, energy, demand, extreme value,total harmonic distortion rate,2-31 harmonic parameters such as wave,voltage and current imbalance,and multi-rate energy metering. The function module can be externally extended.
