Single Phase STS Split Type Prepaid Meter communication as per
IEC62056-21
General introduction
1) Single Phase STS Split Type Prepaid Meter communication as per
IEC62056-21 has the functions such as metering, monitoring, alarm,
display, communication and load control, etc.
2) It adopts STS standard encryption algorithm to exchange the
information based on TOKEN, Advantages of the meter are high
metering accuracy, high level security, strong compatibility, easy
operation, etc.
3) Work with UIU.
Main functions
- UIU communication interface: PLC, RF or twist-wire is optional.
- TOU: Four tariffs; two sets of time zone tables; support public
holidays and weekends; two sets of time period tables.
- Step tariffs
- Friendly power supply: Support emergency credit
- Events logs: Detecting and recording events such as current
reverse, magnetic influence, phase bypass, meter cover open,
terminal cover open, overvoltage, under voltage, etc.
- Anti-tamper: Detecting current reverse, magnetic influence, phase
bypass, meter cover open, terminal cover open etc., at the same
time, the meter can disconnect power supply which is configurable
when the tampers occur.
- Audio and visual alarm: Audio and visual alarm which can be
configurable can be for power flow reverse, magnetic influence,
phase bypass, meter cover open, terminal cover open, etc.
- Load control: Detecting the customer's load status, it can alarm or
disconnect the load when overload.
- Communication interface: Optical port and RS485 interface are
available.

Our advantages
The meter can be used in the Prepaid Power Vending Management
System.repaid power vending management system is based on power
vending management software and database with the devices of
computer, charging machine, prepaid meters, printers and security
modules, etc.It has the following advantages:
1. Archives management: information creating and import for
departments, users .
2. Parameters setting: electricity price, meter configuration, etc.
3. Business management: creating accounts for new meters, meter
changes, meter ownership transfer, customer information
cancellation, power vending, disconnection and reconnection.
4. Data inquiry: power vending inquiry according to date, month,
year, customers, distribution transformers, departments.
5. Data analysis: power vending analysis,drawing, report printing
according to time, customers, distribution transformers, etc.
6. Rights management: operator management, operator password
modification, etc.
Prepaid Power Vending Management System introduction
Prepaid power vending management system is based on power vending
management software and database with the devices of computer,
charging machine, prepaid meters, printers and security modules,
etc. The system can configure the meter parameters, manage power
vending and electricity consumption, it can report and manage data
with effective safety. The system includes remote prepaid, local
prepaid and postpaid functions. The system integrates metering,
electronic, automation and computer technology to realize the
modernization of energy metering, load control, charging, etc.
