Three-phase multifunctional static electricity meters
AMT B0x-FxxTIIx are determined for measurement of active and reactive electric energy, instantaneous active power for consumption and supply, maximum demand, voltage, current and power factor in threephase four wires networks in diredct or indirect connection. They enable measurement of energy in rates controlled by internal clock (up to 4 rates) or externally controlled in two rates.
The measured values stored in registers according to the OBIS codes are displayed on LCD in cyclic or stepping mode. The data are stored in non-volatile memory during power outage. The electricity meters can be parametrized and readout by using optical probe AMOS type and software supplied by the manufacturer. The test pulses indicated by red LED are proportional to the consumed energy.
