How Does A ADL Series Prepayment Energy Meter Work?

How Does A ADL Series Prepayment Energy Meter Work?

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.

ADL Series Prepayment Energy Meter FAQs

  • The difference between a prepaid meter and a metered meter.

    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.

  • Why is this generation divided into card and internal control meters?

    The internal control instrument supports remote recharge, which reduces manpower and maintenance costs and improves user experience.

  • The reason for using wireless prepaid.

    The need of market development. Point scattered, middle equipment is difficult to arrange or the cost is very high.

  • What happens when the prepaid meter runs out

    If the electricity charge runs out, the pre-paid meter will automatically disconnect.like running out of money on your phone
