ADL series prepayment energy meter through measuring the rated frequency of 50Hz single, three-phase AC active energy, with prepayment control, load control, time control and RS485 communication and other functions, to help consumers track their own electricity work, can be free according to their own electricity recharge. It will also remind you when the amount is insufficient based on the customer's past spending history, and automatically power off when the amount is used up, just like a mobile phone.
Metering instruments focus on A variety of power data measurement, power parameter measurement and analysis, power quality measurement, etc. The focus of prepayment table is charging, alarm, control trip and so on.
The internal control instrument supports remote recharge, which reduces manpower and maintenance costs and improves user experience.
The need of market development. Point scattered, middle equipment is difficult to arrange or the cost is very high.
If the electricity charge runs out, the pre-paid meter will automatically disconnect.like running out of money on your phone
