Main Features
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
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
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.
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
With event recording function (including cover-opening event, tamper event and power failure event)
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 of the phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency
