AMT B0x FA4T for DIN rail, for active energy measuring, with LCD and RTC, up to 65 A

Three-phase static electricity meters AMT B0x-FA4T are determined for single-rate and multi-rate measurement of the active energy in direct or indirect connection. The measured values are stored in registers according to the OBIS codes are displayed on LCD in cyclic or stepping mode. They enable to record of the selected energy registers contents (total registers and rates registers) and the maximum demands (MD) registers contents per billing period (max. 6 records). It is also possible to record number of power failure and reverse energy flow occurrences. They enable measurement of energy in rates controlled by internal clock (up to 4 rates) or externally controlled in two rates. The data are stored in non-volatile memory during power outage. The meters can be parametrized and readout using optical probe AMOS and softver AMsoft supplied by the manufacturer. The test pulses indicated by red LED are proportional to the consumed energy. The meters can be produced in version with measurement in summary mode (measurement „using an unidirectional mechanical register“) or with measurement in separation mode (measurement of “consumption – supply”).

Properties
