Single-phase static electricity meters AMS B1x-OAx are determined for direct and indirect measurement of active energy and displaying values on LCD, with measurement of instantaneous RMS values of voltage, current and P.F. The measured values are stored into special registers marked according to the OBIS codes. In cyclic mode the energy at 1 or 2 rates is displayed, in step mode which is controlled by light pen are displayed also other measured values.
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;
- 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.
