General Introduction
CPU Card Electronic Meter Communication As Per DL/T 645-2007 is a
TOU prepayment energy meter. The main functions of the meter are
metering active energy, measuring instantaneous quantity, maximum
demand, recording data of freeze, current loss, broken phase, meter
cover open, overpower alarm, IC card reading/writing, energy charge
balance alarm, energy balance credit and etc.it has multiple
optional functions which can be optional through configure table as
per requirements.

Main functions
● With the export energy metered as total import energy, and
capable of recording export energy alone.
● Prepayment CPU card, higher security and reliability.
● TOU
Four tariffs; two sets of time zone tables; two sets of time period
tables; support public holidays and weekends
● Step tariffs
● Friendly power supply management
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, 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 configured for current reverse,
magnetic influence, phase bypass, meter cover open, etc.
● Load control
Detecting the customer’s load status, it can alarm or disconnect
the power supply when under overload.
● Communication interface
One far infrared interface and one RS485 are available.
Prepaid Power Vending Management System
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.
System advantages
1. The core of the system is based on WINDOWS and it supports
WINDOWS, IOS, ANDROID, it also supports to purchase energy and
inquire records through PC and mobile machine.
2. It supports stand-alone version, network version and mobile
version; the vending modes include TOKEN, card, remote prepaid and
postpaid, etc. It also supports software package automatic
upgrading.
3. It supports multi-languages, functions are modular and can be
customized.
4. The system has strong expansibility and reserve interfaces such
as ATM, bank, APP, distributed vending for easy power purchasing,
historical consumed energy inquiry, printing.
5. System management right is strictly controlled, IP access is
also controlled, and historical login records can be traced.
6. It adopts advanced encryption algorithm and supports several
mediums to transfer the data which is compressed with high speed
and security.
7. The system has the functions such as energy consumption
monitoring, anti-tamper, abnormality alarm, remote load control,
energy statistics and analysis.
