This series of products complies withGB/T 17215-2002《1and2Static AC Active Energy Meter andGB/T 18460.3-2001The requirements of the "Prepaid Electricity Meter" standard. It adopts the currently advanced domestic technologyICCard technology andSMTThe process has the advantages of dual display, accurate measurement, stable accuracy, security and confidentiality, reliable performance, complete functionality, low power consumption, and simple and convenient operation.

1、 Main functions:

This product requires the user to pay and purchase a card to input it into the meter in order for the electricity meter to supply power. Each household has one meter and one card, and the cards are not compatible with each other. After the power in the card is used up, it will automatically trip and cut off the power, effectively solving the problem of difficult electricity collection fees. At the same time, users' electricity purchase information is managed by a microcomputer, making it easy to query, collect, charge, and print receipts.
