Three Phase Smart Prepaid Electric Meter
Three phase smart prepaid electric meter offers options for extended surge protection for lightening up to 13kV and a wide voltage working range -50%~+130%. It is intended for unstable grid voltage environment such as African and Central American continent where brownouts and voltage dips are extremely frequent. The meter works in a three phase four wire network with 100Amp per phase, and 30Vm withstand of RF immunity, allowing it to operate in very severe environments. It is a perfect revenue protection device for sub-metering of residential, light commercial and industrial applications.
Split Configuration for Increased Revenue Protection
The meter consists of two parts, the MCU (Metering & Control Unit) and UIU (User Interface Unit). The MCU and the UIU are linked via galvanic
ally-isolated 2-wire communication cable. Power line carrier (PLC) and Radio Frequency (RF-LoRa) communication is also available on request.
The UIU is installed within consumer's home for prepaid token input and infor inquiry, while MCU is installed in a meter cabinet away from consumers.
Main Features
● 20 digits (Standard Transfer Specification) STS encryption
● DLMS/COSEM standards compliant
● Disconnects on overload and no credit
● Programmable power limit and low creit warning
● Tamper detection and event record such as opening cover, reverse connection, black-out
● Dual power source swap between grid supply and solar with prepayment and post-payment
● Maximum demand measurement and load profiling (on request)
Utility Benefit
● Easy and quick to install with no need of extra communication devices
● Input paymnt control elemets, such as emergency unit, tariff, free basice unit, repayment, fixed charge, VAT etc.
● 4 tariffs /8 time divisions /100 holidays usage recorded on TOU basis
● Flexible AMR AMI setup
