Working principle and structure :
ZMTS4501 single phase electronic kwh meter adopts special large scale integration circuit to measure the KWH the measurement of the kwh consumed by the users through the sampleing of the signal by the voltage separator circuit and the shunt ,processing the A/D converting procedure the digital signal which is processed by the multiplier world be sent to the D/F converter ,the impulse which is output by the converter circuit would drive the register to get the accumulated KWH ,display the electricity consumption velocity by the Kwh indicator ,
