Single Phase DLMS Smart Prepaid Electricity Meter IP54
STE18-G is used in a wide range of intelligent metering
applications.It combines the latest 3DES security encryption
technology and modular communication unit.The meter allows a base
current of 5A, while maintaining a maximum current of 80A and
extending AMR/AMI features.It is a compact design in a BS8565
standard housing, and maintains a robust RF immune tolerance of
30V/m and IP54 rating, allowing it to work in harsh environments.
Moreover, this product belongs to the pre-paid electricity meter,
which can help the supplier to manage the user's use of electricity
and monitor the situation of electricity meter.It is convenient for
suppliers to collect electricity charges and reduces the occurrence
of users defaulting on electricity charges.Users can only use power
if they pay in advance for the amount of power they need to use and
enter TOKENS to recharge.
Our electricity meters can be topped up directly using the Stronpay
vending software and can be topped up remotely via the LORA-RF and
LORA-RF module communicating with the AMI system.AMI is Advanced
Metering Infrastructure. AMI system is mainly composed of Smart
Meter, communication system and equipment, Meter Database
Management system, and Meter Database Management system.MDMS).
Main Features
1. 20 digit (Standard Transfer Specification) STS encryption
2. Detection of significant reverse energy (SRE)
3. IEC62056-21 compliant port allowing for easy data interrogation
4. Disconnects on overload and no credit
5. Dual power source working on both prepaid and credit mode
6. Programmable load limit and low credit warning
7. Detection and record tamper event such as cover open, reversal,
black-out, etc.
8. Easy access to 12 months historical consumption data and last 5
token entered
User Benefit
1. Easy connection to User Interface Unit (UIU) for split type
applications
2. PLC/ RF / GPRS wireless communication with a head-end AMR/AMI
server
3. Time of Use (TOU), multi-tariff, holiday setting.
4. Advanced load control and disconnection features
How to recharge by AMI System? As shown in the figure below:
1. The electricity meter sends information to the Data Concentrator
via LORA-RF or PLC;
2. The Data Concentrator contains Lora-RF/PLC and GPRS modules,
which will transmit the information to the AMI through GPRS after
receiving the information from the water meter.
3. The AMI receives the information, performs remote recharge, and
will generate the recharge TOKEN.It is then sent to the Data
Concentrator via GPRS;
4. Data Concentrator receives the information and sends it to the
electricity meter via LORA-RF or PLC.
