Product Details

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.

Q & A

Q: What kind of requirements do smart energy meter have to load switch?

 

A: ① The load switch of smart energy meter can be divided into internal or external mode.
② When it adopts the internal load switch, the maximum current of energy meter should not be more than 60A.
switch operation shall have Acr suppression measures (hardware or software), and its export loop shall have safety measures for anti false action and being easy to field test. Under the condition of above current, the lifetime of switch shall not be less than 6000 times. Imposing reference voltage on voltage circuit of energy meter, and under the condition of passing 1.2Imax to current circuit, carries out switch on and off test for 10 times; After the test, the energy meter shall work normally; when imposing 70% to 120% reference voltage on voltage circuit of energy meter, the load switch shall work normally.
③ When it adopts external load switch, energy meter shall output a set of switch signals, and the capacity of switch node is AC 250V, 2A. During normal operation, the outgoing switch signals shall maintain load switch closing and allow users to use electricity. When the control conditions are satisfied, the outgoing switch signals shall drive external load switch action and interrupt power supply.
