Prepaid meters are also widely used in other countries, mainly used in rental housing, shopping malls, school and factory dormitories, new energy power generation projects, etc.
The functions of prepaid energy meters are also increasing, not only the original energy measurement, but also remote communication, anti-tamper, rate, event, alarm, load profile, etc. can be increased according to market demand, more intelligent. Prepaid < electricity meter > is also called prepaid < energy meter > .
its main feature is that the user first buys electricity and then uses electricity, the purchased electricity does not continue to purchase electricity after use, the electric energy meter automatically cuts off the power supply to stop the power supply, solving the problem of charging difficulty effectively .
Prepaid meters can be divided into two types in terms of electricity charging mode: code type,refers to the STS standard prepaid meter, and IC card type,refers to the card meter. Currently, the market share of IC card prepaid meters are less and less, they are replaced by code-based prepaid meters.
Today, I will share with you the difference between STS prepaid electric meters and IC card prepaid electricity meters. If you realize these main differences to understand why IC card prepaid electricity meters are replaced by STS prepaid electric meters.
