Single-phase static electricity meters AMS B1x-SAx are determined for direct and indirect measurement of active energy displaying value 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
- The meters can be mounted on the DIN rail (the clips only on request);
- Removable and adjustable upper hinge is included in the package;
- Passive transmitting pulse SO output for remote transmission;
- Indication of voltage presence and reverse energy flow;
- Resistant to external influence;
- 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.
