Three-phase static electricity meters AMT B1x-SxxTE are determined for single-rate active energy measurement in direct and indirect connection, displaying results on mechanical register with stepping motor. In the case of CT (current transformer) operated meters (x/5A) it is necessary value of register to multiply by the current transformer ratio.
The test pulses indicated by red LED are proportional to the consumed energy. Measurement „using an unidirectional mechanical register“ provides positive energy measurement even if the reverse energy flow.
Properties
- Passive transmitting pulse SO output for remote transmission;
- Indication of voltage presence and reverse energy flow;
- Resistant to external influence;
- Welded case on a customer requirement;
- Compliance 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.
