Detecting and recording events such as current reverse, magnetic
influence, phase bypass, meter cover open, terminal cover open,
overvoltage, under voltage, etc.
Detecting current reverse, magnetic influence, phase bypass, meter
cover open, terminal cover open etc, at the same time the meter can
disconnect power supply when the tampers occur which are
configured.
Current reverse, magnetic influence, phase bypass, meter cover
open, terminal cover open can be alarmed which are configured.
- Disconnection /reconnection
Detecting the customer's load status, it can alarm or disconnect
the power supply when overload happens.
Optical port and RS485 interface are available; PLC, RF, GPRS or
twist-wire interface is optional.

Q&A
Q: What is the prepaid power Vending Management System and what are
the advantages of the system?
A:
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.
