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, 14seasontables, 8time zonetables, 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
