Energy meter 1-phase, direct 40A, 1M, MBUS, MID. Energy meter for 4-quadrant measurement with the following accuracy classes: Active energy Class B according to DIN EN 50470-3, active power Class 1 according to IEC 62053-21, active power Class 1 according to IEC 61557-12 and reactive power Class 2 according to IEC 62053-23. The bidirectional meter is MID certified ex works. A sealing set is included in the scope of delivery. Suitable for measuring energy consumption and energy supply in all network systems. Up to 2 tariff counts possible via Mbus. Digital display to show active energy consumed and supplied (kWh). In addition, the real-time measured values for active power (kW), voltage (V), current (A), power factor and frequency (Hz) are displayed with a resolution of up to 7 digits including decimal places. In addition to the previously mentioned measured values, the current measured values of active power (kW), reactive power (kvar) and apparent power (kVA) as well as the power factor can be accessed via Mbus. Wiring errors and connection errors are displayed and the measured data is saved periodically.
