AMT B1x-FxxTxIIxfor active and reactive energy, with RTC and communic., up to 100 A

Three-phase multifunctional static electricity meters AMT B1x-FxxTxIIx 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 direct 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. It is possible to check the data using back-up power supply during this time. The electricity meters can be parametrized and readout by using optical probe AMOS type and software supplied by the manufacturer. The testing pulses are signalling by a red LEDs separately for active and reactive energy. They could be equipped with communication interfaces RS 485 or Mesh module. 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

  • Measurement  of energy, power, maximum demand,  voltage, current, power factor ... (A+, A-, R+, R-, P+, P-, Pmax, U, I, cos j...);
  • Historical records of the selected registers, created in the end of month - maximum 15 month historical records (A+, A-, R+, R-, Pmax);
  • Events records (about missing voltage, covers removal, influence of magnetic field...); number of events and the date of their occurrence;
  • Record data profiles;
  • Passive Impulse outputs SO for remote transmission (particularly for active and reactive energy);
  • Communication interface;
  • Welded case on customer request;
  • Complies with IEC/EN 62052-11 + IEC/EN 62053-21; EN 50470-3 and with requirements of European Parliament and EC Directive 2014/32/EU;
  • Supplied initialy verificated for the billing measurement of active energy.
