AMT B2x-Fx4TxIx (active, reactive & apparent energy), multi-tariff, comm. modules, disconnector

Three-phase static meters AMT B2x-Fx4TxIx measure active, reactive and apparent electrical energy, instantaneous power, maximum demand, voltage, current and power factor in three-phase four-wire networks. Up to four internal tariff periods or two externally controlled tariffs. Configuration and reading via AMOS optical probe and AMsoft software.
