General Introduction
Three Phase Four Wire CPU Card Prepaid Electronic Meter 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.
