Energy Meter STS Prepaid Meters Single Phase Keypad Prepayment Meter Indonesia Market

 

 

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 energyis 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)
