AMT B0x OA4T for DIN rail, for active energy measuring, with LCD, up to 65 A

Three-phase static electricity meters AMT B0x-OA4T are determined for active energy in direct or indirect connection. They are produced in single-rate and double-rate version with external control of the rates. The measured values are 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 performance of internal circuits is monitored during the operation of the meter and the statuses are stored in the particular registers. 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

  • Meter case width 7M (1M = 18 mm);
  • Intended for indoor mounting on DIN rail (35 mm);
  • Passive transmitting pulse SO output for remote transmission;
  • Indication of voltage presence, reverse energy flow and phase sequence;
  • 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.
