Three Phase STS Keypad Prepaid Energy Meter with GPRS communication

Main Features

• Energy Measurement

Total and time-sharing forward active & reactive energy measurement

Total and time-sharing reverse active & reactive energy measurement

Save last one to sixteen months energy data

• 20 digit Standard Transfer Specification(STS)

Credit data transfered from a point of sale (POS) or vending system is made into a numeric token  in a 20 digit number using the Standard Transfer Specification (STS) encryption techniques, which comply with IEC62055 protocol

• Load control function

When the residual energy is 0 or the allowable overdraft that both sides agreed, this meter will send out power-off signal to have load switch cut off power. The power will be recovered automatically after inputting new purchased energy amount.

• Programmable low credit warning

The meter can be programmed for 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

• Tamper detection

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

• Max. Demand Measurement

Measure total and time-sharing forward active & reactive maximum demand and time of occurred

Measure total and time-sharing reverse active & reactive maximum demand and time of occurred

Measure total forward & reverse apparent maximum demand and time of occurred

• Real Time Measurement

Real-time measurement of the phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency

• TOU

4tariffs, 100holidays, 14season tables, 8time zone tables, each table on maximum 14 time zones

• Event Log

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