High Accuracy Single Phase Smart Card Prepayment Digital Electronic
Smart Card Prepayment Energy Meter used the entire digitized
electronic meter special-purpose chip group. Take integrated
circuit card as to pay the bill with the control medium complete
digitized intelligence electronic metering device. It is an ideal
product on the current situation of reforming electric power
consuming system, commercializing electric power, solving the
problems of the collection of charges, as well as adjusting load
state of electrical network.
