LCD Display Prepaid Energy Meters Three Phase Four Wire Meter Contactless RF Card

Three phase prepayment electronic meter used the entire digitized electronic meter special-purpose chip group. Take integrated circuit card(IC card) as to pay the bill with the control medium complete digitized intelligence electronic metering device. It's a new generation of products, it has the complete digitized electrical energy measurement, the intellectualized charge control and the user information management the multi-purpose functions and so on. And it is an ideal product on the current situation of reforming electric power consuming system, commercializing electric power, solving the problem of the collection of charges, as well as adjusting load state of electrical network.

1. Technical parameters:

2. Main Features:

2.1 Energy Measurement

Total and time-sharing forward active & reactiveenergy measurement

Total and time-sharing reverse active & reactiveenergy measurement

Save last one to sixteen months energy data

2.2 Load control function

When the residual energy is0 or the allowable overdraft that both sides agreed, this

meter will send out poweroff signal to have load switch cut off power.

The power will be recovered

automatically after inputting new purchased energy amount.

2.3 Programmable low credit warning

The meter can be programmedfor setting user credit warning threshold, When the

meter’s residual energy is equal to credit warning threshold, the meter will start the

audio & video warning function in a way of warning light flashing

2.4 Tamper detection

With event recording function (includingcover-opening event, tamper event and power failure event)

1.5 Max. Demand Measurement

Measure total and forward active & reactive maximumdemand and time of occurred

Measure total and reverse active & reactive maximumdemand and time of occurred

Measure total forward & reverse apparent maximumdemand and time of occurred

2.6 Real Time Measurement

Realtime measurement of the phase voltage, current,total active power, reactive power, apparent power,

total power factor, powergrid frequency

2.7 TOU

4tariffs, 100holidays, 14season‐tables, 8time zone‐tables, each table onmaximum 14 time zones

2.8 Event Log

The last 10 records of following events:Power-down,Programing, Cover opening, Terminal cover opening, Reverse power, PhaseFail.the records include data and time

2.9 Optical port interface
