Measure Two sources of electricity energy, one is GRID which is post-paid function,
another is Diesel Generator which is prepaid function, and the meter and switch automaticly.
Load control functionWhen 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 warningThe 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 flashingTamper detectionWith event recording function (including cover-opening event, tamper event and power failure event)Max.
