The three-phase IC card prepaid energy meter and the card insertion style energy meter are similar in nature, using the card insertion method for electricity consumption. However, the latter uses IC electronic cards, which have certain restrictions on the types of cards. The use of IC card prepaid method replaces traditional manual meter reading and charging, improving work efficiency and saving a lot of manpower, material resources and cost investment. It is the best product for the power department to achieve automation of electricity billing management and load management to solve the problem of difficult charging and overdue electricity bills. It can be used as an important way in the future power grid automation management mode, and is very suitable for the power department to use it for power users.

The power source of the three-phase IC card prepaid energy meter comes from the three-phase active energy metering function. This device can count the reverse power into the forward power without any problems. The display screen adopts an LCD liquid crystal display screen, which is very clear, accurate, and reliable in terms of numbers and current usage. In terms of safety, alarm tripping and over power alarm tripping functions are adopted, which can emit alarm sounds in the first time to remind users to pay attention to safety when safety accidents and problems occur. In order to ensure the normal and stable use of electricity for many busy people who forget to pay, a credit function has been added.
