Three Phase Four Wire Prepaid Energy Meters Card Prepayment KWH Meter LCD Display

Traditional prepaid electric meter is normally working by the means of Multi-Card One Meter, electricity consumption measurement or No Card to deduct the purchased electricity (unit: kWh ) after being inserted into IC Card. However, the price fluctuation of electricity market which cannot reflect in the purchased electricity will increase the losses of Power Company.

For this purpose, a new designed prepaid electric meter Model No. DTSY150 D/F/A issued by Radarking adopts the electricity fee ( Unit: CNY) way, that is, when the fee is transmitted into through Client IC Card and the meter will deduct the price of electricity ( 0.1kWh as base ) according to the unit price, which is set on the IC Card to be transferred into the meter. When the electricity rate changes, the unit price of electricity in the meter will also be changed through the communication medium IC card that the modified unit price are written into from the vending system.

1. Main Features: 

1.1 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

1.2 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.

1.3 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

1.4 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

1.6 Real Time Measurement

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

total power factor, powergrid frequency

1.7 TOU

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

1.8 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

1.9 Optical port interface
