Measures and accumulates import and export energy in the same register, and the energy will be accumulated into total active energy and active
energy of each billing month. The total active energy register will be the sum of the addition of the forward and reverse energy resistances.
Bidirectional active energy measurement, reverse energy accumulated to positive energy.
Monitor active demand, voltage, current, active power, power factor and supply frequency
Switchable between modes: prepaid and postpaid as needed.
Multi-level remaining power, the meter will alarm when the remaining power is low.
LED alarm for tampering (optional audible alarm)
Credit overflow limit: If the credit amount transferred plus remaining credit more than credit stock limit, then the credit amount transferred will be refused,
but the Credit amount transfer token is still valid.
Multi-tariff (optional), programmable remotely.
Open upper cover and terminal cover detection whether the meter is power on or off.
Switch off when the power is over the set value
LED pulse light output.
Design the meter according to IEC 62055-41, IEC62055-31, and IEC 62055-51.
Complete recording of time stamped events including current reversal, overvoltage, undervoltage, overload, power failure, time synchronization, power purchase, with the last 10 events of each stored.
High reliability and accuracy, easy to use.
