DDSY1598 DLMS Single Phase Smart STS G3-PLC Split Din Rail Prepaid Meter

DDSY1598 Single Phase Smart DLMS STS G3-PLC Split Din Rail Prepaid Meter

I. General Introduction of Din Rail Prepaid Meter 

DDSY1598 Single Phase Smart DLMS STS G3-PLC Split Din Rail Prepaid Meter takes digital medium as information exchange media. It is an active electric energy meter in which users load in pre-purchased energy and it takes energy as its billing to realize the functions of active power measuring and pre-payment control. MCU and CIU communicate via PLC. MCU includes measurement unit, real-time clock unit, load switch and other auxiliary equipments, while CIU includes numeric keypad interface and display.

II. Technical Features of Din Rail Prepaid Meter 

i.  Overload limit

ii. Bypass function

iii.Reverse current detection

iv.Terminal cover opening detection

v. Switching between operating mode and non-operating mode

vi.Switching between pre-payment and post-payment mode.

<< Standard Transfer Specification (STS)
The single phase Din Rail prepaid meter complies with the standard transfer specifications.
Secure data transfer with 20-digit STS encryption, compliant with IEC62055 protocol

<< Programmable Low Credit Warning The Din Rail prepaid meter can be programmed with two level credit thresholds When the remaining credit is higher than the first threshold, it means that the remaining credit is sufficient. When the remaining credit is lower than the first threshold, it means that the remaining credit is low When the remaining credit is lower than the second threshold, it means that the remaining credit is very low. Credit level alarm trigger threshold in prepayment mode -Remaining credit>29KWh, Credit LED remains green
-15KWh< Remaining credit <=29KWh, Credit LED is red
-5KWh< Remaining credit <=15KWh, Credit LED is flashing red
-0KWh< Remaining credit <=5KWh, Credit LED: is flashing red with the audible alarm beeping
-Remaining credit =0KWh, Credit LED is red with the audible alarm continuously for 3 minutes, and the power will be cut off. << Three-color LED credit indicator
When the remaining credit is sufficient, the credit LED indicator will be green
When the remaining credit is low, the credit LED indicator will be yellow
When the remaining credit is very low, the credit LED indicator will be RED

<< Anti-fraud functions
In addition to the seal protection, the energy meter has the anti-fraud features that cut off the customer’s supply in the event that the terminal cover is opened or the top cover is opened. A fraud code issued by an authorized person is required for service to resume.

<< Power control management
The built-in relay will be automatically disconnected
1. Credit is exhausted
2. Overload occurs
3. Meter cover is opened etc.
<< Tamper detection and event log
The latest 50 records of the following events: Power off, Programming, Cover opening,
Power Reverse, Phase Failure etc. Records include data and time

<< Communication
1. With optical (infrared) port which conforms to IEC62056-21 protocol for meter data reading
2. The communication between MCU and CIU can adopt cable, G3-PLC (Power Line Carrier) or RF (Radio Frequency) with the communication distance 1000~1500 meters
