Energy meter 1-phase, direct 40A, 1M, S0, 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. A sealing set is included in the scope of delivery. Suitable for measuring energy consumption and energy supply in all network systems. 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. Active energy (kWh) and reactive energy (kvarh) consumed and supplied are output via pulse. All measured values and energy values are also output via an IR interface. Wiring errors and connection errors are displayed and the measurement data is saved periodically.
