Three-phase static electricity meters AMT B3x-OA4SET are determined for direct measurement of active energy with measured consumption displaying on LCD. They are manufactured in single-rate and double-rate versions with external switching of rates.
Properties
- Passive transmitting pulse SO output for remote transmission;
- Energy, voltage and current measurement;
- Event records (about influence of magnetic field, missing voltage, covers removal,...) – number of events;
- Welded case on a customer requirement;
- Complies with IEC/EN 62052-11, IEC/EN 62053-21;
EN 50470-1, EN 50470-3 and with requirements of European Parliament and EC Directive 2014/32/EU (MID); - It is supplied initially verificated for billing measurement.
