Project Description
DDSY1598 DLMS Smart Single Phase STS Keypad Prepaid Energy Meter
DDSY1598 smart single phase prepaid energy meter adopts latest integrated SOC solution, equipping with built-in relay. Then, it will cut off the customer’s power supply once tamper events occur. Generally, tamper events include opening of terminal cover or front cover, and over load. At the same time, it complies with DLMS/COSEM too. Further more, prepaid meter supports Standard Transfer Specification (STS) and Currency Transfer Specification (CTS). However, when user exhausted available credit or “emergency credit”, prepaid energy meters will disconnect customer’s power supply immediately. Finally, it can link with Customer Interface Unit (CIU) by cable or communication module like PLC or RF.
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). |
| Double measuring elements: 01 on phase and 01 on neutral. |
| 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. |
