Project Description
DDSY1598 Single Phase Smart Prepaid Energy Meter with 2G or 4G communication module with RF CIU
Single Phase Smart Prepaid Energy Meter is an advanced electricity meter that allows users to pay for electricity before they use it, similar to how prepaid mobile phone services work. These meters are designed to improve energy efficiency, reduce electricity theft, and give consumers more control over their energy consumption.
Firstly: Key Features of Smart Prepaid Energy Meter
Secondly: How smart prepaid energy meter works
(1) The user recharges the meter with a certain amount of money.
(2) The meter converts this amount into energy units (kWh).
(3) As the user consumes electricity, the balance decreases.
(4) When the balance reaches zero, the meter automatically disconnects the power supply.
(5) Users can recharge again to restore electricity.
Thirdly: Event detection, recording function of Smart Prepaid Energy Meter
(1) Power outage detection and recording
(2) Purchase record
(3) When meter cover is open, meter’s relay trips off.
(4) When terminal cover is open, meter’s relay trips off.
(5) When communication cover is open, meter’s relay trips off.
(6) Over voltage
(7) Under voltage
Function&Feature
| Programmable low credit alert & have an alarm based on a minimum credit threshold. The meter can be programmed to set user credit alert threshold. |
| When the remaining credit in the meter is exhausted, the relay built into the meter will automatically cut off the power to the load. Customer’s power will be restored after recharging. |
| The 8-digit LCD screen displays the acceptance or rejection of a 20-digit token. |
| When you open the terminal cover or the meter cover when the power is on, the meter cuts off the power supply and signals the anomaly (on the LCD screen and by LED). You need an anti-fraud code (maintenance tokens to reconnect the integrated contactor). |
| Neutral measurement is optional |
| In the case of detection of a bypass current, the meter will integrate the highest value of the current for the measurement of the active energy. |
| Recent 10 times purchase charging TOKEN with time flag can be recorded and checked. |
| Programmable lower voltage or higher voltage threshold. |
| Alternate prepayment mode to postpaid by special TOKEN code. |
