Credit Mode Relay Prepaid Electric Meter Multi - Function Four wires Enery Meter
Calin's prepaid meters own anti-tamper features .The meter is built with multi sensors and triggers. including tamper shutdown protection ,disconnects on overload and no credit .The CA368-M works with a plug & play wireless communication module. A utility and service provider can select from Power Line Carrier (PLC) Radio Frequency (RF) LoRa, and GSM .
The CA368-M is the next generation of prepaid electricity meters and they can offer a range of intelligent functionality. It is a digital meter that records your usage in hourly increments. This allows for complex billing to be applied such as Time of Use (TOU) and Demand kVA charges.
Automatic meter reading for balance verification is carried out as a scheduled task from the central server from time to time. Consumers are allowed to check their balance anytime via access to an online account and to use a diversity of payment channels such as point of sale kiosk, online payment ( need collaboration with bank), or any third party payment platform that interfaces with the vending merchant system within the central server, to purchase credit.
The credit is remotely topped up by the server once transaction is confirmed. This feature provides a utility and service provider dynamic monitoring and control over the supply and offers the consumers utmost convenience to buy electricity and budget their usage as well.
