Main Functions
| Prepaid function | users can only get electricity after payment |
| Alarm for low credit | buzzer will constantly give alarm when low credit |
| Function of load control | meter can be programmed for load control threshold, If the current power is more than threshold. The meter will cut off user load |
| Available for self-testing | it can test LCD and relay etc. and report the results directly |
| Available for anti-tamper | meter will automatically close the valve after detection of magnetic field and open cover event |
| Available for TOU tariff | TOU tariff can be set on request |
| Overdraft Collection | electricity overdraft can be collected day by day or month by month |
| Recording the event | meter can record the tamper event, open cover event, purchase event and TOKENS |
Application
| Count electricity consumption over users’ period time. When the meter runs out of power, a warning is issued, and the main system can remotely control the switch and disconnect the network, so the user can no longer use the power. Only when the user recharges and enters the corresponding TOKENS, the network will be connected remotely and the user can continue to use it. In this way, the user can avoid the situation that the user defaults on the electricity bill but continues to use electricity endlessly, and help the supplier to better manage the user. |
