AMS B3x-Fx for active energy, with RTC

Single-phase static electricity meters AMS B3x-Fx are determined for measurement of active energy, instantaneous active power, voltage, current and power factor in single-phase 2-wire network in direct connection. They enable record of the selected energy registers contents (total and rate) for billing period (max. 15 records). The electricity meters are equipped with internal real time clock (RTC) which is used for switching of maximum four rates. It is also possible to record events, such as, for example, voltage outage, terminal block cover removal, meter cover removal and magnetic field influence.

Properties

  • Measurement  of energy, power, voltage, current, power factor ... (+A, -A, +P, -P, U, I, cos j...);
  • Removable and adjustable upper hinge is included in the package;
  • Historical records of the selected registers contents created in the end of month - maximum 15 month historical records;
  • Event records (about influence of magnetic field, missing voltage, covers removal...) – number and time of their occurrence;
  • Passive impulse SO output;
  • 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 (MID);
  • It is supplied initially verificated for billing measurement.
